RC.CONF(5)		    BSD	File Formats Manual		    RC.CONF(5)

NAME
     rc.conf --	system configuration information

DESCRIPTION
     The file rc.conf contains descriptive information about the local host
     name, configuration details for any potential network interfaces and
     which services should be started up at system initial boot	time.  In new
     installations, the	rc.conf	file is	generally initialized by the system
     installation utility.

     The purpose of rc.conf is not to run commands or perform system startup
     actions directly.	Instead, it is included	by the various generic startup
     scripts in	/etc which conditionalize their	internal actions according to
     the settings found	there.

     The /etc/rc.conf file is included from the	file /etc/defaults/rc.conf,
     which specifies the default settings for all the available	options.  Op-
     tions need	only be	specified in /etc/rc.conf when the system administra-
     tor wishes	to override these defaults.  The file /etc/rc.conf.local is
     used to override settings in /etc/rc.conf for historical reasons.

     The sysrc(8) command provides a scripting interface to modify system con-
     fig files.

     In	addition to /etc/rc.conf.local you can also place smaller configura-
     tion files	for each rc(8) script in the /etc/rc.conf.d directory or
     <dir>/rc.conf.d directories specified in local_startup, which will	be in-
     cluded by the load_rc_config function.  For jail configurations you could
     use the file /etc/rc.conf.d/jail to store jail specific configuration op-
     tions.  If	local_startup contains /usr/local/etc/rc.d and /opt/conf,
     /usr/local/rc.conf.d/jail and /opt/conf/rc.conf.d/jail will be loaded.
     If	<dir>/rc.conf.d/<name> is a directory, all of files in the directory
     will be loaded.  Also see the rc_conf_files variable below.

     Options are set with "name=value" assignments that	use sh(1) syntax.  The
     following list provides a name and	short description for each variable
     that can be set in	the rc.conf file:

     rc_debug	 (bool)	If set to "YES", enable	output of debug	messages from
		 rc scripts.  This variable can	be helpful in diagnosing mis-
		 takes when editing or integrating new scripts.	 Beware	that
		 this produces copious output to the terminal and syslog(3).

     rc_info	 (bool)	If set to "NO",	disable	informational messages from
		 the rc	scripts.  Informational	messages are displayed when a
		 condition that	is not serious enough to warrant a warning or
		 an error occurs.

     rc_startmsgs
		 (bool)	If set to "YES", show "Starting	foo:" when faststart
		 is used (e.g.,	at boot	time).

     early_late_divider
		 (str) The name	of the script that should be used as the de-
		 limiter between the "early" and "late"	stages of the boot
		 process.  The early stage should contain all the services
		 needed	to get the disks (local	or remote) mounted so that the
		 late stage can	include	scripts	contained in the directories
		 listed	in the local_startup variable (see below).  Thus, the
		 two likely candidates for this	value are mountcritlocal for
		 the typical system, and mountcritremote if the	system needs
		 remote	file systems mounted to	get access to the
		 local_startup directories; for	example	when /usr/local	is NFS
		 mounted.  For rc.conf within a	jail(8)	NETWORKING is likely
		 to be an appropriate value.  Extreme care should be taken
		 when changing this value, and before changing it one should
		 ensure	that there are adequate	provisions to recover from a
		 failed	boot (such as physical contact with the	machine, or
		 reliable remote console access).

     always_force_depends
		 (bool)	Various	rc.d scripts use the force_depend function to
		 check whether required	services are already running, and to
		 start them if necessary.  By default during boot time this
		 check is bypassed if the required service is enabled in
		 /etc/rc.conf[.local].	Setting	this option will bypass	that
		 check at boot time and	always test whether or not the service
		 is actually running.  Enabling	this option is likely to in-
		 crease	your boot time if services are enabled that utilize
		 the force_depend check.

     <name>_chroot
		 (str) chroot(8) to this directory before running the service.

     <name>_user
		 (str) Run the service under this user account.

     <name>_group
		 (str) Run the chrooted	service	under this system group.  Un-
		 like the _user	setting, this setting has no effect if the
		 service is not	chrooted.

     <name>_fib	 (int) The setfib(1) value to run the service under.

     <name>_nice
		 (int) The nice(1) value to run	the service under.

     apm_enable	 (bool)	If set to "YES", enable	support	for Automatic Power
		 Management with the apm(8) command.

     apmd_enable
		 (bool)	Run apmd(8) to handle APM event	from userland.	This
		 also enables support for APM.

     apmd_flags	 (str) If apmd_enable is set to	"YES", these are the flags to
		 pass to the apmd(8) daemon.

     devd_enable
		 (bool)	Run devd(8) to handle device added, removed or unknown
		 events	from the kernel.

     ddb_enable	 (bool)	Run ddb(8) to install ddb(4) scripts at	boot time.

     ddb_config	 (str) Configuration file for ddb(8).  Default /etc/ddb.conf.

     kld_list	 (str) A list of kernel	modules	to load	right after the	local
		 disks are mounted.  Loading modules at	this point in the boot
		 process is much faster	than doing it via /boot/loader.conf
		 for those modules not necessary for mounting local disk.

     kldxref_enable
		 (bool)	Set to "NO" by default.	 Set to	"YES" to automatically
		 rebuild linker.hints files with kldxref(8) at boot time.

     kldxref_clobber
		 (bool)	Set to "NO" by default.	 If kldxref_enable is true,
		 setting to "YES" will overwrite existing linker.hints files
		 at boot time.	Otherwise, only	missing	linker.hints files are
		 generated.

     kldxref_module_path
		 (str) Empty by	default.  A semi-colon (`;') delimited list of
		 paths containing kld(4) modules.  If empty, the contents of
		 the kern.module_path sysctl(8)	are used.

     powerd_enable
		 (bool)	If set to "YES", enable	the system power control fa-
		 cility	with the powerd(8) daemon.

     powerd_flags
		 (str) If powerd_enable	is set to "YES", these are the flags
		 to pass to the	powerd(8) daemon.

     tmpmfs	 Controls the creation of a /tmp memory	file system.  Always
		 happens if set	to "YES" and never happens if set to "NO".  If
		 set to	anything else, a memory	file system is created if /tmp
		 is not	writable.

     tmpsize	 Controls the size of a	created	/tmp memory file system.

     tmpmfs_flags
		 Extra options passed to the mdmfs(8) utility when the memory
		 file system for /tmp is created.  The default is "-S",	which
		 inhibits the use of softupdates on /tmp so that file system
		 space is freed	without	delay after file truncation or dele-
		 tion.	See mdmfs(8) for other options you can use in
		 tmpmfs_flags.

     varmfs	 Controls the creation of a /var memory	file system.  Always
		 happens if set	to "YES" and never happens if set to "NO".  If
		 set to	anything else, a memory	file system is created if /var
		 is not	writable.

     varsize	 Controls the size of a	created	/var memory file system.

     varmfs_flags
		 Extra options passed to the mdmfs(8) utility when the memory
		 file system for /var is created.  The default is "-S",	which
		 inhibits the use of softupdates on /var so that file system
		 space is freed	without	delay after file truncation or dele-
		 tion.	See mdmfs(8) for other options you can use in
		 varmfs_flags.

     populate_var
		 Controls the automatic	population of the /var file system.
		 Always	happens	if set to "YES"	and never happens if set to
		 "NO".	If set to anything else, a memory file system is cre-
		 ated if /var is not writable.	Note that this process re-
		 quires	access to certain commands in /usr before /usr is
		 mounted on normal systems.

     cleanvar_enable
		 (bool)	Clean the /var directory.

     local_startup
		 (str) List of directories to search for startup script	files.

     script_name_sep
		 (str) The field separator to use for breaking down the	list
		 of startup script files into individual filenames.  The de-
		 fault is a space.  It is not necessary	to change this unless
		 there are startup scripts with	names containing spaces.

     hostapd_enable
		 (bool)	Set to "YES" to	start hostapd(8) at system boot	time.

     hostname	 (str) The fully qualified domain name (FQDN) of this host on
		 the network.  This should almost certainly be set to some-
		 thing meaningful, even	if there is no network connection.  If
		 dhclient(8) is	used to	set the	hostname via DHCP, this	vari-
		 able should be	set to an empty	string.	 Within	a jail(8) the
		 hostname is generally already set and this variable may ab-
		 sent.	If this	value remains unset when the system is done
		 booting your console login will display the default hostname
		 of "Amnesiac".

     nisdomainname
		 (str) The NIS domain name of this host, or "NO" if NIS	is not
		 used.

     dhclient_program
		 (str) Path to the DHCP	client program (/sbin/dhclient,	the
		 OpenBSD DHCP client, is the default).

     dhclient_flags
		 (str) Additional flags	to pass	to the DHCP client program.
		 For the OpenBSD DHCP client, see the dhclient(8) manpage for
		 a description of the command line options available.

     dhclient_flags_<iface>
		 Additional flags to pass to the DHCP client program running
		 on iface only.	 When specified, this variable overrides
		 dhclient_flags.

     background_dhclient
		 (bool)	Set to "YES" to	start the DHCP client in background.
		 This can cause	trouble	with applications depending on a work-
		 ing network, but it will provide a faster startup in many
		 cases.

     background_dhclient_<iface>
		 When specified, this variable overrides the
		 background_dhclient variable for interface iface only.

     synchronous_dhclient
		 (bool)	Set to "YES" to	start dhclient(8) synchronously	at
		 startup.  This	behavior can be	overridden on a	per-interface
		 basis by replacing the	"DHCP" keyword in the
		 ifconfig_<interface> variable with "SYNCDHCP" or
		 "NOSYNCDHCP".

     defaultroute_delay
		 (int) When set	to a positive value, wait up to	this long af-
		 ter configuring DHCP interfaces at startup to give the	inter-
		 faces time to receive a lease.

     firewall_enable
		 (bool)	Set to "YES" to	load firewall rules at startup.	 If
		 the kernel was	not built with options IPFIREWALL, the ipfw.ko
		 kernel	module will be loaded.	See also ipfilter_enable.

     firewall_script
		 (str) This variable specifies the full	path to	the firewall
		 script	to run.	 The default is	/etc/rc.firewall.

     firewall_type
		 (str) Names the firewall type from the	selection in
		 /etc/rc.firewall, or the file which contains the local	fire-
		 wall ruleset.	Valid selections from /etc/rc.firewall are:

		 open	 unrestricted IP access
		 closed	 all IP	services disabled, except via "lo0"
		 client	 basic protection for a	workstation
		 simple	 basic protection for a	LAN.

		 If a filename is specified, the full path must	be given.

     firewall_quiet
		 (bool)	Set to "YES" to	disable	the display of firewall	rules
		 on the	console	during boot.

     firewall_logging
		 (bool)	Set to "YES" to	enable firewall	event logging.	This
		 is equivalent to the IPFIREWALL_VERBOSE kernel	option.

     firewall_logif
		 (bool)	Set to "YES" to	create pseudo interface	ipfw0 for log-
		 ging.	For more details, see ipfw(8) manual page.

     firewall_flags
		 (str) Flags passed to ipfw(8) if firewall_type	specifies a
		 filename.

     firewall_coscripts
		 (str) List of executables and/or rc scripts to	run after
		 firewall starts/stops.	 Default is empty.

     firewall_nat_enable
		 (bool)	The ipfw(8) equivalent of natd_enable.	Setting	this
		 to "YES" enables kernel NAT.  firewall_enable must also be
		 set to	"YES".

     firewall_nat_interface
		 (str) The ipfw(8) equivalent of natd_interface.  This is the
		 name of the public interface or IP address on which kernel
		 NAT should run.

     firewall_nat_flags
		 (str) Additional configuration	parameters for kernel NAT
		 should	be placed here.

     dummynet_enable
		 (bool)	Setting	this to	"YES" will automatically load the
		 dummynet(4) module if firewall_enable is also set to "YES".

     ipfw_netflow_enable
		 (bool)	Setting	this to	"YES" will enable netflow logging via
		 ng_netflow(4)

		 By default a ipfw rule	is inserted and	all packets are	dupli-
		 cated with the	ngtee command and netflow packets are sent to
		 127.0.0.1 on the netflow port using protocol version 5.

     ipfw_netflow_hook
		 (int) netflow hook name, must be numerical (default 9995).

     ipfw_netflow_rule
		 (int) ipfw rule number	(default 1000).

     ipfw_netflow_ip
		 (str) Destination server ip for receiving netflow data	(de-
		 fault 127.0.0.1).

     ipfw_netflow_port
		 (int) Destination server port for receiving netflow data (de-
		 fault 9995).

     ipfw_netflow_version
		 (int) Do not set for using version 5 of the netflow protocol,
		 set it	to 9 for using version 9.

     ipfw_netflow_fib
		 (int) Only match packet in FIB	ipfw_netflow_fib (default is
		 undefined meaning all FIBs).

     natd_program
		 (str) Path to natd(8).

     natd_enable
		 (bool)	Set to "YES" to	enable natd(8).	 firewall_enable must
		 also be set to	"YES", and divert(4) sockets must be enabled
		 in the	kernel.	 If the	kernel was not built with options
		 IPDIVERT, the ipdivert.ko kernel module will be loaded.

     natd_interface
		 (str) This is the name	of the public interface	on which
		 natd(8) should	run.  The interface may	be given as an inter-
		 face name or as an IP address.

     natd_flags	 (str) Additional natd(8) flags	should be placed here.	The -n
		 or -a flag is automatically added with	the above
		 natd_interface	as an argument.

     ipfilter_enable
		 (bool)	Set to "NO" by default.	 Setting this to "YES" enables
		 ipf(8)	packet filtering.

		 Typical usage will require putting

		 ipfilter_enable="YES"
		 ipnat_enable="YES"
		 ipmon_enable="YES"
		 ipfs_enable="YES"

		 into /etc/rc.conf and editing /etc/ipf.rules and
		 /etc/ipnat.rules appropriately.

		 Note that ipfilter_enable and ipnat_enable can	be enabled in-
		 dependently.  ipmon_enable and	ipfs_enable both require at
		 least one of ipfilter_enable and ipnat_enable to be enabled.

		 Having

		 options IPFILTER
		 options IPFILTER_LOG
		 options IPFILTER_DEFAULT_BLOCK

		 in the	kernel configuration file is a good idea, too.

     ipfilter_program
		 (str) Path to ipf(8) (default /sbin/ipf).

     ipfilter_rules
		 (str) Set to /etc/ipf.rules by	default.  This variable	con-
		 tains the name	of the filter rule definition file.  The file
		 is expected to	be readable for	the ipf(8) command to execute.

     ipv6_ipfilter_rules
		 (str) Set to /etc/ipf6.rules by default.  This	variable con-
		 tains the IPv6	filter rule definition file.  The file is ex-
		 pected	to be readable for the ipf(8) command to execute.

     ipfilter_flags
		 (str) Empty by	default.  This variable	contains flags passed
		 to the	ipf(8) program.

     ipnat_enable
		 (bool)	Set to "NO" by default.	 Set it	to "YES" to enable
		 ipnat(8) network address translation.	See ipfilter_enable
		 for a detailed	discussion.

     ipnat_program
		 (str) Path to ipnat(8)	(default /sbin/ipnat).

     ipnat_rules
		 (str) Set to /etc/ipnat.rules by default.  This variable con-
		 tains the name	of the file holding the	network	address	trans-
		 lation	definition.  This file is expected to be readable for
		 the ipnat(8) command to execute.

     ipnat_flags
		 (str) Empty by	default.  This variable	contains flags passed
		 to the	ipnat(8) program.

     ipmon_enable
		 (bool)	Set to "NO" by default.	 Set it	to "YES" to enable
		 ipmon(8) monitoring (logging ipf(8) and ipnat(8) events).
		 Setting this variable needs setting ipfilter_enable or
		 ipnat_enable too.  See	ipfilter_enable	for a detailed discus-
		 sion.

     ipmon_program
		 (str) Path to ipmon(8)	(default /sbin/ipmon).

     ipmon_flags
		 (str) Set to "-Ds" by default.	 This variable contains	flags
		 passed	to the ipmon(8)	program.  Another typical example
		 would be "-D /var/log/ipflog" to have ipmon(8)	log directly
		 to a file bypassing syslogd(8).  Make sure to adjust
		 /etc/newsyslog.conf in	such case like this:

		 /var/log/ipflog  640  10  100	*  Z  /var/run/ipmon.pid

     ipfs_enable
		 (bool)	Set to "NO" by default.	 Set it	to "YES" to enable
		 ipfs(8) saving	the filter and NAT state tables	during shut-
		 down and reloading them during	startup	again.	Setting	this
		 variable needs	setting	ipfilter_enable	or ipnat_enable	to
		 "YES" too.  See ipfilter_enable for a detailed	discussion.
		 Note that if kern_securelevel is set to 3, ipfs_enable	cannot
		 be used because the raised securelevel	will prevent ipfs(8)
		 from saving the state tables at shutdown time.

     ipfs_program
		 (str) Path to ipfs(8) (default	/sbin/ipfs).

     ipfs_flags	 (str) Empty by	default.  This variable	contains flags passed
		 to the	ipfs(8)	program.

     pf_enable	 (bool)	Set to "NO" by default.	 Setting this to "YES" enables
		 pf(4) packet filtering.

		 Typical usage will require putting

		       pf_enable="YES"

		 into /etc/rc.conf and editing /etc/pf.conf appropriately.
		 Adding

		       device pf

		 builds	support	for pf(4) into the kernel, otherwise the ker-
		 nel module will be loaded.

     pf_rules	 (str) Path to pf(4) ruleset configuration file	(default
		 /etc/pf.conf).

     pf_program	 (str) Path to pfctl(8)	(default /sbin/pfctl).

     pf_flags	 (str) If pf_enable is set to "YES", these flags are passed to
		 the pfctl(8) program when loading the ruleset.

     pflog_enable
		 (bool)	Set to "NO" by default.	 Setting this to "YES" enables
		 pflogd(8) which logs packets from the pf(4) packet filter.

     pflog_logfile
		 (str) If pflog_enable is set to "YES" this controls where
		 pflogd(8) stores the logfile (default /var/log/pflog).	 Check
		 /etc/newsyslog.conf to	adjust logfile rotation	for this.

     pflog_program
		 (str) Path to pflogd(8) (default /sbin/pflogd).

     pflog_flags
		 (str) Empty by	default.  This variable	contains additional
		 flags passed to the pflogd(8) program.

     pflog_instances
		 (str) If logging to more than one pflog(4) interface is de-
		 sired,	pflog_instances	is set to the list of pflogd(8)	in-
		 stances that should be	started	at system boot time.  If
		 pflog_instances is set, for each whitespace-separated element
		 in the	list, <element>_dev and	<element>_logfile elements are
		 assumed to exist.  <element>_dev must contain the pflog(4)
		 interface to be watched by the	named pflogd(8)	instance.
		 <element>_logfile must	contain	the name of the	logfile	that
		 will be used by the pflogd(8) instance.

     ftpproxy_enable
		 (bool)	Set to "NO" by default.	 Setting this to "YES" enables
		 ftp-proxy(8) which supports the pf(4) packet filter in	trans-
		 lating	ftp connections.

     ftpproxy_flags
		 (str) Empty by	default.  This variable	contains additional
		 flags passed to the ftp-proxy(8) program.

     ftpproxy_instances
		 (str) Empty by	default.  If multiple instances	of
		 ftp-proxy(8) are desired at boot time,	ftpproxy_instances
		 should	contain	a whitespace-separated list of instance	names.
		 For each element in the list, a variable named
		 <element>_flags should	be defined, containing the command-
		 line flags to be passed to the	ftp-proxy(8) instance.

     pfsync_enable
		 (bool)	Set to "NO" by default.	 Setting this to "YES" enables
		 exposing pf(4)	state changes to other hosts over the network
		 by means of pfsync(4).	 The pfsync_syncdev variable must also
		 be set	then.

     pfsync_syncdev
		 (str) Empty by	default.  This variable	specifies the name of
		 the network interface pfsync(4) should	operate	through.  It
		 must be set accordingly if pfsync_enable is set to "YES".

     pfsync_syncpeer
		 (str) Empty by	default.  This variable	is optional.  By de-
		 fault,	state change messages are sent out on the synchronisa-
		 tion interface	using IP multicast packets.  The protocol is
		 IP protocol 240, PFSYNC, and the multicast group used is
		 224.0.0.240.  When a peer address is specified	using the
		 pfsync_syncpeer option, the peer address is used as a desti-
		 nation	for the	pfsync traffic,	and the	traffic	can then be
		 protected using ipsec(4).  See	the pfsync(4) manpage for more
		 details about using ipsec(4) with pfsync(4) interfaces.

     pfsync_ifconfig
		 (str) Empty by	default.  This variable	can contain additional
		 options to be passed to the ifconfig(8) command used to set
		 up pfsync(4).

     tcp_extensions
		 (bool)	Set to "YES" by	default.  Setting this to "NO" dis-
		 ables certain TCP options as described	by RFC 1323.  Setting
		 this to "NO" might help remedy	such problems with connections
		 as randomly hanging or	other weird behavior.  Some network
		 devices are known to be broken	with respect to	these options.

     log_in_vain
		 (int) Set to 0	by default.  The sysctl(8) variables,
		 net.inet.tcp.log_in_vain and net.inet.udp.log_in_vain,	as de-
		 scribed in tcp(4) and udp(4), are set to the given value.

     tcp_keepalive
		 (bool)	Set to "YES" by	default.  Setting to "NO" will disable
		 probing idle TCP connections to verify	that the peer is still
		 up and	reachable.

     tcp_drop_synfin
		 (bool)	Set to "NO" by default.	 Setting to "YES" will cause
		 the kernel to ignore TCP frames that have both	the SYN	and
		 FIN flags set.	 This prevents OS fingerprinting, but may
		 break some legitimate applications.

     icmp_drop_redirect
		 (bool)	Set to "NO" by default.	 Setting to "YES" will cause
		 the kernel to ignore ICMP REDIRECT packets.  Refer to icmp(4)
		 for more information.

     icmp_log_redirect
		 (bool)	Set to "NO" by default.	 Setting to "YES" will cause
		 the kernel to log ICMP	REDIRECT packets.  Note	that the log
		 messages are not rate-limited,	so this	option should only be
		 used for troubleshooting networks.  Refer to icmp(4) for more
		 information.

     icmp_bmcastecho
		 (bool)	Set to "YES" to	respond	to broadcast or	multicast ICMP
		 ping packets.	Refer to icmp(4) for more information.

     ip_portrange_first
		 (int) If not set to "NO", this	is the first port in the de-
		 fault portrange.  Refer to ip(4) for more information.

     ip_portrange_last
		 (int) If not set to "NO", this	is the last port in the	de-
		 fault portrange.  Refer to ip(4) for more information.

     network_interfaces
		 (str) Set to the list of network interfaces to	configure on
		 this host or "AUTO" (the default) for all current interfaces.
		 Setting the network_interfaces	variable to anything other
		 than the default is deprecated.  Interfaces that the adminis-
		 trator	wishes to store	configuration for, but not start at
		 boot should be	configured with	the "NOAUTO" keyword in	their
		 ifconfig_<interface> variables	as described below.

		 An ifconfig_<interface> variable is also assumed to exist for
		 each value of interface.  When	an interface name contains any
		 of the	characters ".-/+" they are translated to "_" before
		 lookup.  The variable can contain arguments to	ifconfig(8),
		 as well as special case-insensitive keywords described	below.
		 Such keywords are removed before passing the value to
		 ifconfig(8) while the order of	the other arguments is pre-
		 served.

		 It is possible	to add IP alias	entries	using ifconfig(8) syn-
		 tax with the address family keyword such as inet.  Assuming
		 that the interface in question	was ed0, it might look some-
		 thing like this:

		 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

		 It also possible to configure multiple	IP addresses in	Class-
		 less Inter-Domain Routing (CIDR) address notation, whose each
		 address component can be a range like inet 192.0.2.5-23/24 or
		 inet6 2001:db8:1-f::1/64.  This notation allows address and
		 prefix	length part only, not the other	address	modifiers.
		 Note that the maximum number of the generated addresses from
		 a range specification is limited to an	integer	value speci-
		 fied in netif_ipexpand_max in rc.conf because a small typo
		 can unexpectedly generate a large number of addresses.	 The
		 default value is 2048.	 It can	be increased by	adding the
		 following line	into rc.conf:

		 netif_ipexpand_max="4096"

		 In the	case of	192.0.2.5-23/24, the address 192.0.2.5 will be
		 configured with the netmask /24 and the addresses 192.0.2.6
		 to 192.0.2.23 with the	non-conflicting	netmask	/32 as ex-
		 plained in the	ifconfig(8) alias section.  Note that this
		 special netmask handling is only for inet, not	for the	other
		 address families such as inet6.

		 With the interface in question	being ed0, an example could
		 look like:

		 ifconfig_ed0_alias2="inet 192.0.2.129/27"
		 ifconfig_ed0_alias3="inet 192.0.2.1-5/28"

		 and so	on.

		 Note that ipv4_addrs_<interface> variable was supported for
		 IPv4 CIDR address notation.  It is now	deprecated because the
		 functionality was integrated into
		 ifconfig_<interface>_alias<n> though ipv4_addrs_<interface>
		 is still supported for	backward compatibility.

		 For each ifconfig_<interface>_alias<n>	entry with an address
		 family	keyword, its contents are passed to ifconfig(8).  Exe-
		 cution	stops at the first unsuccessful	access,	so if some-
		 thing like this is present:

		 ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
		 ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
		 ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"

		 Then note that	alias4 would not be added since	the search
		 would stop with the missing "alias3" entry.  Because of this
		 difficult to manage behavior, there is
		 ifconfig_<interface>_aliases variable,	which has the same
		 functionality as ifconfig_<interface>_alias<n>	and can	have
		 all of	entries	in a variable like the following:

		 ifconfig_ed0_aliases="\
			 inet 127.0.0.251 netmask 0xffffffff \
			 inet 127.0.0.252 netmask 0xffffffff \
			 inet 127.0.0.253 netmask 0xffffffff \
			 inet 127.0.0.254 netmask 0xffffffff"

		 It also supports CIDR notation.

		 If the	/etc/start_if.<interface> file is present, it is read
		 and executed by the sh(1) interpreter before configuring the
		 interface as specified	in the ifconfig_<interface> and
		 ifconfig_<interface>_alias<n> variables.

		 If a vlans_<interface>	variable is set, a vlan(4) interface
		 will be created for each item in the list with	the vlandev
		 argument set to interface.  If	a vlan interface's name	is a
		 number, then that number is used as the vlan tag and the new
		 vlan interface	is named interface.tag.	 Otherwise, the	vlan
		 tag must be specified via a vlan parameter in the
		 create_args_<interface> variable.

		 To create a vlan device named em0.101 on em0 with the vlan
		 tag 101 and the optional the IPv4 address 192.0.2.1/24:

		 vlans_em0="101"
		 ifconfig_em0_101="inet	192.0.2.1/24"

		 To create a vlan device named myvlan on em0 with the vlan tag
		 102:

		 vlans_em0="myvlan"
		 create_args_myvlan="vlan 102"

		 If a wlans_<interface>	variable is set, an wlan(4) interface
		 will be created for each item in the list with	the wlandev
		 argument set to interface.  Further wlan cloning arguments
		 may be	passed to the ifconfig(8) create command by setting
		 the create_args_<interface> variable.	One or more wlan(4)
		 devices must be created for each wireless devices as of
		 FreeBSD 8.0.  Debugging flags for wlan(4) devices as set by
		 wlandebug(8) may be specified with an wlandebug_<interface>
		 variable.  The	contents of this variable will be passed di-
		 rectly	to wlandebug(8).

		 If the	ifconfig_<interface> contains the keyword "NOAUTO"
		 then the interface will not be	configured at boot or by
		 /etc/pccard_ether when	network_interfaces is set to "AUTO".

		 It is possible	to bring up an interface with DHCP by adding
		 "DHCP"	to the ifconfig_<interface> variable.  For instance,
		 to initialize the ed0 device via DHCP,	it is possible to use
		 something like:

		 ifconfig_ed0="DHCP"

		 If you	want to	configure your wireless	interface with
		 wpa_supplicant(8) for use with	WPA, EAP/LEAP or WEP, you need
		 to add	"WPA" to the ifconfig_<interface> variable.

		 On the	other hand, if you want	to configure your wireless in-
		 terface with hostapd(8), you need to add "HOSTAP" to the
		 ifconfig_<interface> variable.	 hostapd(8) will use the set-
		 tings from /etc/hostapd-<interface>.conf

		 Finally, you can add ifconfig(8) options in this variable, in
		 addition to the /etc/start_if.<interface> file.  For in-
		 stance, to configure an ath(4)	wireless device	in station
		 mode with an address obtained via DHCP, using WPA authentica-
		 tion and 802.11b mode,	it is possible to use something	like:

		 wlans_ath0="wlan0"
		 ifconfig_wlan0="DHCP WPA mode 11b"

		 In addition to	the ifconfig_<interface> form, a fallback
		 variable ifconfig_DEFAULT may be configured.  It will be used
		 for all interfaces with no ifconfig_<interface> variable.
		 This is intended to replace the no longer supported
		 pccard_ifconfig variable.

		 It is also possible to	rename an interface by doing:

		 ifconfig_ed0_name="net0"
		 ifconfig_net0="inet 192.0.2.1 netmask 0xffffff00"

     ipv6_enable
		 (bool)	This variable is deprecated.  Use
		 ifconfig_<interface>_ipv6 and ipv6_activate_all_interfaces if
		 necessary.

		 If the	variable is "YES", "inet6 accept_rtadv"	is added to
		 all of	ifconfig_<interface>_ipv6 and the
		 ipv6_activate_all_interfaces is defined as "YES".

     ipv6_prefer
		 (bool)	This variable is deprecated.  Use ip6addrctl_policy
		 instead.

		 If the	variable is "YES", the default address selection pol-
		 icy table set by ip6addrctl(8)	will be	IPv6-preferred.

		 If the	variable is "NO", the default address selection	policy
		 table set by ip6addrctl(8) will be IPv4-preferred.

     ipv6_activate_all_interfaces
		 (bool)	This controls initial configuration on IPv6-capable
		 interfaces with no corresponding ifconfig_<interface>_ipv6
		 variable.  Note that it is not	always necessary to set	this
		 variable to "YES" to use IPv6 functionality on	FreeBSD.  In
		 most cases, just configuring ifconfig_<interface>_ipv6	vari-
		 ables works.

		 If the	variable is "NO", all interfaces which do not have a
		 corresponding ifconfig_<interface>_ipv6 variable will be
		 marked	as "IFDISABLED"	at creation.  This means that all of
		 IPv6 functionality on that interface is completely disabled
		 to enforce a security policy.	If the variable	is set to
		 "YES",	the flag will be cleared on all	of the interfaces.

		 In most cases,	just defining an ifconfig_<interface>_ipv6 for
		 an IPv6-capable interface should be sufficient.  However, if
		 an interface is added dynamically (by some tunneling
		 protocols such	as PPP,	for example), it is often difficult to
		 define	the variable in	advance.  In such a case, configuring
		 the "IFDISABLED" flag can be disabled by setting this vari-
		 able to "YES".

		 For more details of the "IFDISABLED" flag and keywords	"inet6
		 ifdisabled", see ifconfig(8).

		 Default is "NO".

     ipv6_privacy
		 (bool)	If the variable	is "YES" privacy addresses will	be
		 generated for each IPv6 interface as described	in RFC 4941.

     ipv6_network_interfaces
		 (str) This is the IPv6	equivalent of network_interfaces.
		 Normally manual configuration of this variable	is not needed.

     ipv6_cpe_wanif
		 (str) If the variable is set to an interface name, the
		 ifconfig(8) options "inet6 -no_radr accept_rtadv" will	be
		 added to the specified	interface automatically	before evalu-
		 ating ifconfig_<interface>_ipv6, and two sysctl(8) variables
		 net.inet6.ip6.rfc6204w3 and net.inet6.ip6.no_radr will	be set
		 to 1.

		 This means the	specified interface will accept	ICMPv6 Router
		 Advertisement messages	on that	link and add the discovered
		 routers into the Default Router List.	While the other	inter-
		 faces can still accept	RA messages if the "inet6
		 accept_rtadv" option is specified, adding routes into the De-
		 fault Router List will	be disabled by "inet6 no_radr" option
		 by default.  See ifconfig(8) for more details.

		 Note that ICMPv6 Router Advertisement messages	will be	ac-
		 cepted	even when net.inet6.ip6.forwarding is 1	(packet
		 forwarding is enabled)	when net.inet6.ip6.rfc6204w3 is	set to
		 1.

		 Default is "NO".

     ifconfig_<interface>_descr
		 (str) This assigns arbitrary description to an	interface.
		 The sysctl(8) variable	net.ifdescr_maxlen limits its length.
		 This static setting may be overridden by commands started
		 with dynamic interface	configuration utilities	like
		 dhclient(8) hooks. The	description can	be seen	with
		 ifconfig(8) command and it may	be exported with bsnmpd(1)
		 daemon	using its MIB-2	module.

     ifconfig_<interface>_ipv6
		 (str) IPv6 functionality on an	interface should be configured
		 by ifconfig_<interface>_ipv6, instead of setting ifconfig pa-
		 rameters in ifconfig_<interface>.  If this variable is	empty,
		 all of	IPv6 configurations on the specified interface by
		 other variables such as ipv6_prefix_<interface> will be ig-
		 nored.

		 Aliases should	be set by ifconfig_<interface>_alias<n>	with
		 "inet6" keyword.  For example:

		 ifconfig_ed0_ipv6="inet6 2001:db8:1::1	prefixlen 64"
		 ifconfig_ed0_alias0="inet6 2001:db8:2::1 prefixlen 64"

		 Interfaces that have an "inet6	accept_rtadv" keyword in
		 ifconfig_<interface>_ipv6 setting will	be automatically con-
		 figured by SLAAC (StateLess Address AutoConfiguration)	de-
		 scribed in RFC	4862.

		 Note that a link-local	address	will be	automatically config-
		 ured in addition to the configured global-scope addresses be-
		 cause the IPv6	specifications require it on each link.	 The
		 address is calculated from the	MAC address by using an	algo-
		 rithm defined in RFC 4862, Section 5.3.

		 If only a link-local address is needed	on the interface, the
		 following configuration can be	used:

		 ifconfig_ed0_ipv6="inet6 auto_linklocal"

		 A link-local address can also be configured manually.	This
		 is useful for the default router address of an	IPv6 router so
		 that it does not change when the network interface card is
		 replaced.  For	example:

		 ifconfig_ed0_ipv6="inet6 fe80::1 prefixlen 64"

     ipv6_prefix_<interface>
		 (str) If one or more prefixes are defined in
		 ipv6_prefix_<interface> addresses based on each prefix	and
		 the EUI-64 interface index will be configured on that inter-
		 face.	Note that this variable	will be	ignored	when
		 ifconfig_<interface>_ipv6 is empty.

		 For example, the following configuration

		 ipv6_prefix_ed0="2001:db8:1:0 2001:db8:2:0"

		 is equivalent to the following:

		 ifconfig_ed0_alias0="inet6 2001:db8:1:: eui64 prefixlen 64"
		 ifconfig_ed0_alias1="inet6 2001:db8:1:: prefixlen 64 anycast"
		 ifconfig_ed0_alias2="inet6 2001:db8:2:: eui64 prefixlen 64"
		 ifconfig_ed0_alias3="inet6 2001:db8:2:: prefixlen 64 anycast"

		 These Subnet-Router anycast addresses will be added only when
		 ipv6_gateway_enable is	YES.

     ipv6_default_interface
		 (str) If not set to "NO", this	is the default output inter-
		 face for scoped addresses.  This works	only with ipv6_gate-
		 way_enable="NO".

     ip6addrctl_enable
		 (bool)	This variable is to enable configuring default address
		 selection policy table	(RFC 3484).  The table can be speci-
		 fied in another variable ip6addrctl_policy.  For
		 ip6addrctl_policy the following keywords can be specified:
		 "ipv4_prefer",	"ipv6_prefer", or "AUTO".

		 If "ipv4_prefer" or "ipv6_prefer" is specified, ip6addrctl(8)
		 installs a pre-defined	policy table described in Section 2.1
		 (IPv6-preferred) or 10.3 (IPv4-preferred) of RFC 3484.

		 If "AUTO" is specified, it attempts to	read a file
		 /etc/ip6addrctl.conf first.  If this file is found,
		 ip6addrctl(8) reads and installs it.  If not found, a policy
		 is automatically set according	to
		 ipv6_activate_all_interfaces variable;	if the variable	is set
		 to "YES" the IPv6-preferred one is used.  Otherwise IPv4-pre-
		 ferred.

		 The default value of ip6addrctl_enable	and ip6addrctl_policy
		 are "YES" and "AUTO", respectively.

     cloned_interfaces
		 (str) Set to the list of clonable network interfaces to cre-
		 ate on	this host.  Further cloning arguments may be passed to
		 the ifconfig(8) create	command	for each interface by setting
		 the create_args_<interface> variable.	If an interface	name
		 is specified with ":sticky" keyword, the interface will not
		 be destroyed even when	rc.d/netif script is invoked with
		 "stop"	argument.  This	is useful when reconfiguring the in-
		 terface without destroying it.	 Entries in cloned_interfaces
		 are automatically appended to network_interfaces for configu-
		 ration.

     cloned_interfaces_sticky
		 (bool)	This variable is to globally enable functionality of
		 ":sticky" keyword in cloned_interfaces	for all	interfaces.
		 The default value is "NO".  Even if this variable is speci-
		 fied to "YES",	":nosticky" keyword can	be used	to override it
		 on per	interface basis.

     gif_interfaces
		 (str) This variable is	deprecated in favor of
		 cloned_interfaces.  Set to the	list of	gif(4) tunnel inter-
		 faces to configure on this host.  For each gif	tunnel inter-
		 face, set a variable named ifconfig_<interface> with the pa-
		 rameters for the ifconfig(8) command to configure the link
		 level for interface with the tunnel option.  The value	of
		 this variable is used to configure the	link layer of the tun-
		 nel using the tunnel option to	ifconfig.  For example,	con-
		 figure	two gif	interfaces with:

		       gif_interfaces="gif0 gif1"
		       ifconfig_gif0="tunnel src_addr0 dst_addr0"
		       ifconfig_gif1="tunnel src_addr1 dst_addr1"

		 Additionally, this option ensures that	each listed interface
		 is created via	the create option to ifconfig.	This example
		 also works with cloned_interfaces instead of gif_interfaces.

     sppp_interfaces
		 (str) Set to the list of sppp(4) interfaces to	configure on
		 this host.  A spppconfig_<interface> variable is assumed to
		 exist for each	value of interface.  Each interface should
		 also be configured by a general ifconfig_<interface> setting.
		 Refer to spppcontrol(8) for more information about available
		 options.

     ppp_enable	 (bool)	If set to "YES", run the ppp(8)	daemon.

     ppp_profile
		 (str) The name	of the profile to use from /etc/ppp/ppp.conf.
		 Also used for per-profile overrides of	ppp_mode and ppp_nat,
		 and ppp_<profile>_unit.  When the profile name	contains any
		 of the	characters ".-/+" they are translated to "_" for the
		 proposes of the override variable names.

     ppp_mode	 (str) Mode in which to	run the	ppp(8) daemon.

     ppp_<profile>_mode
		 (str) Overrides the global ppp_mode for profile.  Accepted
		 modes are "auto", "ddial", "direct" and "dedicated".  See the
		 manual	for a full description.

     ppp_nat	 (bool)	If set to "YES", enables network address translation.
		 Used in conjunction with gateway_enable allows	hosts on pri-
		 vate network addresses	access to the Internet using this host
		 as a network address translating router.

     ppp_<profile>_nat
		 (str) Overrides the global ppp_nat for	profile.

     ppp_<profile>_unit
		 (int) Set the unit number to be used for this profile.	 See
		 the manual description	of -unitN for details.

     ppp_user	 (str) The name	of the user under which	ppp(8) should be
		 started.  By default, ppp(8) is started as "root".

     rc_conf_files
		 (str) This option is used to specify a	list of	files that
		 will override the settings in /etc/defaults/rc.conf.  The
		 files will be read in the order in which they are specified
		 and should include the	full path to the file.	By default,
		 the files specified are /etc/rc.conf and /etc/rc.conf.local

     zfs_enable	 (bool)	If set to "YES", /etc/rc.d/zfs will attempt to auto-
		 matically mount ZFS file systems and initialize ZFS volumes
		 (ZVOLs).

     gptboot_enable
		 (bool)	If set to "YES", /etc/rc.d/gptboot will	log if the
		 system	successfully (or not) booted from a GPT	partition,
		 which had the bootonce	attribute set using gpart(8) utility.

     gbde_autoattach_all
		 (bool)	If set to "YES", /etc/rc.d/gbde	will attempt to	auto-
		 matically initialize your .bde	devices	in /etc/fstab.

     gbde_devices
		 (str) List the	devices	that the script	should try to attach,
		 or "AUTO".

     gbde_lockdir
		 (str) The directory where the gbde(4) lockfiles are located.
		 The default lockfile directory	is /etc.

		 The lockfile for each individual gbde(4) device can be	over-
		 ridden	by setting the variable	gbde_lock_<device>, where
		 device	is the encrypted device	without	the "/dev/" and	".bde"
		 parts.

     gbde_attach_attempts
		 (int) Number of times to attempt attaching to a gbde(4) de-
		 vice, i.e., how many times the	user is	asked for the pass-
		 phrase.  Default is 3.

     geli_devices
		 (str) List of devices to automatically	attach on boot.	 Note
		 that .eli devices from	/etc/fstab are automatically appended
		 to this list.

     geli_groups
		 (str) List of groups containing devices to automatically at-
		 tach on boot with the same keyfiles and passphrase.  This
		 must be accompanied with a corresponding geli_<group>_devices
		 variable.

     geli_tries	 (int) Number of times user is asked for the pass-phrase.  If
		 empty,	it will	be taken from kern.geom.eli.tries sysctl vari-
		 able.

     geli_default_flags
		 (str) Default flags to	use by geli(8) when configuring	disk
		 encryption.  Flags can	be configured for every	device sepa-
		 rately	by defining the	geli_<device>_flags variable, and for
		 every group separately	by defining the	geli_<group>_flags
		 variable.

     geli_autodetach
		 (str) Specifies if GELI devices should	be marked for detach
		 on last close after file systems are mounted.	Default	is
		 "YES".	 This can be changed for every device separately by
		 defining the geli_<device>_autodetach variable.

     root_rw_mount
		 (bool)	Set to "YES" by	default.  After	the file systems are
		 checked at boot time, the root	file system is remounted as
		 read-write if this is set to "YES".  Diskless systems that
		 mount their root file system from a read-only remote NFS
		 share should set this to "NO" in their	rc.conf.

     fsck_y_enable
		 (bool)	If set to "YES", fsck(8) will be run with the -y flag
		 if the	initial	preen of the file systems fails.

     background_fsck
		 (bool)	If set to "NO",	the system will	not attempt to run
		 fsck(8) in the	background where possible.

     background_fsck_delay
		 (int) The amount of time in seconds to	sleep before starting
		 a background fsck(8).	It defaults to sixty seconds to	allow
		 large applications such as the	X server to start before disk
		 I/O bandwidth is monopolized by fsck(8).  If set to a nega-
		 tive number, the background file system check will be delayed
		 indefinitely to allow the administrator to run	it at a	more
		 convenient time.  For example it may be run from cron(8) by
		 adding	a line like

		       0 4 * * * root /etc/rc.d/bgfsck forcestart

		 to /etc/crontab.

     netfs_types
		 (str) List of file system types that are network-based.  This
		 list should generally not be modified by end users.  Use
		 extra_netfs_types instead.

     extra_netfs_types
		 (str) If set to something other than "NO" (the	default), this
		 variable extends the list of file system types	for which au-
		 tomatic mounting at startup by	rc(8) should be	delayed	until
		 the network is	initialized.  It should	contain	a whitespace-
		 separated list	of network file	system descriptor pairs, each
		 consisting of a file system type as passed to mount(8)	and a
		 human-readable, one-word description, joined with a colon
		 (`:').	 Extending the default list in this way	is only	neces-
		 sary when third party file system types are used.

     syslogd_enable
		 (bool)	If set to "YES", run the syslogd(8) daemon.

     syslogd_program
		 (str) Path to syslogd(8) (default /usr/sbin/syslogd).

     syslogd_flags
		 (str) If syslogd_enable is set	to "YES", these	are the	flags
		 to pass to syslogd(8).

     inetd_enable
		 (bool)	If set to "YES", run the inetd(8) daemon.

     inetd_program
		 (str) Path to inetd(8)	(default /usr/sbin/inetd).

     inetd_flags
		 (str) If inetd_enable is set to "YES",	these are the flags to
		 pass to inetd(8).

     hastd_enable
		 (bool)	If set to "YES", run the hastd(8) daemon.

     hastd_program
		 (str) Path to hastd(8)	(default /sbin/hastd).

     hastd_flags
		 (str) If hastd_enable is set to "YES",	these are the flags to
		 pass to hastd(8).

     local_unbound_enable
		 (bool)	If set to "YES", run the unbound(8) daemon as a	local
		 caching resolver.

     kdc_enable	 (bool)	Set to "YES" to	start a	Kerberos 5 authentication
		 server	at boot	time.

     kdc_program
		 (str) If kdc_enable is	set to "YES" this is the path to Ker-
		 beros 5 Authentication	Server.

     kdc_flags	 (str) Empty by	default.  This variable	contains additional
		 flags to be passed to the Kerberos 5 authentication server.

     kadmind_enable
		 (bool)	Set to "YES" to	start kadmind(8), the Kerberos 5 Ad-
		 ministration Daemon; set to "NO" on a slave server.

     kadmind_program
		 (str) If kadmind_enable is set	to "YES" this is the path to
		 Kerberos 5 Administration Daemon.

     kpasswdd_enable
		 (bool)	Set to "YES" to	start kpasswdd(8), the Kerberos	5
		 Password-Changing Daemon; set to "NO" on a slave server.

     kpasswdd_program
		 (str) If kpasswdd_enable is set to "YES" this is the path to
		 Kerberos 5 Password-Changing Daemon.

     kfd_enable	 (bool)	Set to "YES" to	start kfd(8), the Kerberos 5 ticket
		 forwarding daemon, at the boot	time.

     kfd_program
		 (str) Path to kfd(8) (default /usr/libexec/kfd).

     rwhod_enable
		 (bool)	If set to "YES", run the rwhod(8) daemon at boot time.

     rwhod_flags
		 (str) If rwhod_enable is set to "YES",	these are the flags to
		 pass to it.

     amd_enable	 (bool)	If set to "YES", run the amd(8)	daemon at boot time.

     amd_flags	 (str) If amd_enable is	set to "YES", these are	the flags to
		 pass to it.  See the amd(8) manpage for more information.

     amd_map_program
		 (str) If set, the specified program is	run to get the list of
		 amd(8)	maps.  For example, if the amd(8) maps are stored in
		 NIS, one can set this to run ypcat(1) to get a	list of	amd(8)
		 maps from the amd.master NIS map.

     update_motd
		 (bool)	If set to "YES", /etc/motd will	be updated at boot
		 time to reflect the kernel release being run.	If set to
		 "NO", /etc/motd will not be updated.

     nfs_client_enable
		 (bool)	If set to "YES", run the NFS client daemons at boot
		 time.

     nfs_access_cache
		 (int) If nfs_client_enable is set to "YES", this can be set
		 to "0"	to disable NFS ACCESS RPC caching, or to the number of
		 seconds for which NFS ACCESS results should be	cached.	 A
		 value of 2-10 seconds will substantially reduce network traf-
		 fic for many NFS operations.

     nfs_server_enable
		 (bool)	If set to "YES", run the NFS server daemons at boot
		 time.

     nfs_server_flags
		 (str) If nfs_server_enable is set to "YES", these are the
		 flags to pass to the nfsd(8) daemon.

     nfsv4_server_enable
		 (bool)	If nfs_server_enable is	set to "YES" and
		 nfsv4_server_enable are set to	"YES", enable the server for
		 NFSv4 as well as NFSv2	and NFSv3.

     nfsuserd_enable
		 (bool)	If nfsuserd_enable is set to "YES", run	the nfsuserd
		 daemon, which is needed for NFSv4 in order to map between
		 user/group names vs uid/gid numbers.  If nfsv4_server_enable
		 is set	to "YES", this will be forced enabled.

		 to "YES".  The	moused(8) daemon is able to detect the appro-
		 priate	mouse type automatically in many cases.	 Set this
		 variable to "auto" to let the daemon detect it, or select one
		 from the following list if the	automatic detection fails.

		 If the	mouse is attached to the PS/2 mouse port, choose
		 "auto"	or "ps/2", regardless of the brand and model of	the
		 mouse.	 Likewise, if the mouse	is attached to the bus mouse
		 port, choose "auto" or	"busmouse".  All other protocols are
		 for serial mice and will not work with	the PS/2 and bus mice.
		 If this is a USB mouse, "auto"	is the only protocol type
		 which will work.

		 microsoft	 Microsoft mouse (serial)
		 intellimouse	 Microsoft IntelliMouse	(serial)
		 mousesystems	 Mouse systems Corp. mouse (serial)
		 mmseries	 MM Series mouse (serial)

		 Even if the mouse is not in the above list, it	may be compat-
		 ible with one in the list.  Refer to the manual page for
		 moused(8) for compatibility information.

		 It should also	be noted that while this is enabled, any other
		 client	of the mouse (such as an X server) should access the
		 mouse through the virtual mouse device, /dev/sysmouse,	and
		 configure it as a "sysmouse" type mouse, since	all mouse data
		 is converted to this single canonical format when using
		 moused(8).  If	the client program does	not support the
		 "sysmouse" type, specify the "mousesystems" type.  It is the
		 second	preferred type.

     moused_port

		 When moused_nondefault_enable is enabled, and a moused(8)
		 daemon	is started for a non-default port, the
		 moused_XXX_flags set of options has precedence	over and re-
		 places	the default moused_flags (where	XXX is the name	of the
		 non-default port, i.e., ums0).	 By setting moused_XXX_flags
		 it is possible	to set up a different set of default flags for
		 each moused(8)	instance.  For example,	you can	use "-3" for
		 the default moused_flags to make your laptop's	touchpad more
		 comfortable to	use, but an empty set of options for
		 moused_ums0_flags when	your usb(4) mouse has three or more
		 buttons.

     mousechar_start
		 (int) If set to "NO", the default mouse cursor	character
		 range 0xd0-0xd3 is used, otherwise the	range start is set to

		 is occupied in	the language code table.

     allscreens_flags
		 (str) If set, vidcontrol(1) is	run with these options for
		 each of the virtual terminals (/dev/ttyv*).  For example, "-m
		 on" will enable the mouse pointer on all virtual terminals if
		 moused_enable is set to "YES".

     allscreens_kbdflags
		 (str) If set, kbdcontrol(1) is	run with these options for

     jail_* variables
		 Note that older releases supported per-jail configuration via
		 rc.conf variables.  For example, hostname of a	jail named
		 vjail was able	to be set by jail_vjail_hostname.  These per-
		 jail configuration variables are now obsolete in favor	of
		 jail(8) configuration file.  For backward compatibility, when
		 per-jail configuration	variables are defined, jail(8) config-
		 uration files are created as /var/run/jail.<jname>.conf and
		 used.

		 The following per-jail	parameters are handled by rc.d/jail
		 script	out of their corresponding rc.conf variables.  In ad-
		 dition	to them, parameters in jail_<jname>_parameters will be
		 added to the configuration file.  They	must be	a semi-colon
		 (`;') delimited list of "key=value".  For more	details, see
		 jail(8) manual	page.

		 within	the specified time (in seconds).  Notice that in addi-
		 tion to this soft timeout, init(8) also applies a hard	time-
		 out for the execution of rc.shutdown.	This is	configured via
		 sysctl(8) variable kern.init_shutdown_timeout and defaults to
		 120 seconds.  Setting the value of rcshutdown_timeout to more
		 than 120 seconds will have no effect until the	sysctl(8)
		 variable kern.init_shutdown_timeout is	also increased.

		 (str) Optional	arguments passed to newfs(8) to	initialize
		 md(4) device X.

     mdconfig_md<X>_owner

     autobridge_interfaces
		 (str) Set to the list of bridge interfaces that will have
		 newly arriving	interfaces checked against to be automatically
		 added.	 If not	set to "NO" then for each whitespace separated
		 element in the	value, a autobridge_<element> variable is as-
		 sumed to exist	which has a whitespace separated list of in-
		 terface names to match, these names can use wildcards.	 For
		 example:

		 autobridge_interfaces="bridge0"

		 put of	usbconfig(8) on	your system to find this information.

     netwait_enable
		 (bool)	If set to "YES", delays	the start of network-reliant
		 services until	netwait_if is up and ICMP packets to a desti-
		 nation	defined	in netwait_ip are flowing.  Link state is ex-
		 amined	first, followed	by "pinging" an	IP address to verify
		 network usability.  If	no destination can be reached or time-
		 outs are exceeded, network services are started anyway	with
		 no guarantee that the network is usable.  Use of this vari-
		 able requires both netwait_ip and netwait_if to be set.

     netwait_ip	 (str) Empty by	default.  This variable	contains a space-de-
		 limited list of IP addresses to ping(8).  DNS hostnames
		 should	not be used as resolution is not guaranteed to be

		 fault is 60.

     netwait_if	 (str) Empty by	default.  Defines the name of the network in-
		 terface on which watch	for link.  ifconfig(8) is used to mon-
		 itor the interface, looking for "status: no carrier".	Once
		 gone, the link	is considered up.  This	can be a vlan(4) in-
		 terface if desired.

     netwait_if_timeout
		 (int) Defines the total number	of seconds to wait for link to
		 become	usable,	polled at a 1-second interval.	The default is
		 30.
