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, sysinstall(8).

     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.
     Options need only be specified in /etc/rc.conf when the system adminis-
     trator wishes to override these defaults.	The file /etc/rc.conf.local is
     used to override settings in /etc/rc.conf for historical reasons.	See
     the rc_conf_files variable	below.

     The following list	provides a name	and short description for each vari-
     able 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
		 mistakes 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.

     swapfile	 (str) If set to ``NO'', no swapfile is	installed, otherwise
		 the value is used as the full pathname	to a file to use for
		 additional swap space.

     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.

     kldxref_enable
		 (bool)	Set to ``NO'' by default.  Set to ``YES'' to automati-
		 cally 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.

     pccard_enable
		 (bool)	If set to ``YES'', enable PCCARD support at boot time.

     pccard_mem	 (str) Set to PCCARD controller	memory address or ``DEFAULT''
		 for the default value.

     pccard_ifconfig
		 (str) List of arguments to be passed to ifconfig(8) at	boot
		 time or on insertion of the card (e.g.	``inet 192.168.1.1
		 netmask 255.255.255.0'' for a fixed address or	``DHCP'' for a
		 DHCP client).

     pccard_beep
		 (int) If 0, set the PCCARD controller to silent mode.	If 1,
		 set it	to beep	mode.  If 2, set it to melody mode.

     pccard_conf
		 (str) Path to the configuration file for the pccardd(8) dae-
		 mon (e.g. /etc/pccard.conf.sample).

     pccardd_flags
		 (str) If pccard_enable	is set to ``YES'', these are the flags
		 to pass to the	pccardd(8) daemon.

     pccard_ether_delay
		 (str) Set the delay before starting dhclient(8) in the
		 /etc/pccard_ether script.  This defaults to 5 seconds to work
		 around	a bug in the ed(4) driver which	can lead to system
		 hangs when using some newer ed(4) based cards.

     removable_interfaces
		 (str) List of removable network interfaces to be supported by
		 /etc/pccard_ether.

     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
		 default is a space.  It is not	necessary to change this
		 unless	there are startup scripts with names containing	spa-
		 ces.

     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.

     ipv6_enable
		 (bool)	Enable support for IPv6	networking.  Note that this
		 requires that the kernel have been compiled with options
		 INET6.

     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
		 ISC DHCP client, is the default).

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

     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.

     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.

     ipv6_firewall_enable
		 (bool)	The IPv6 equivalent of firewall_enable.	 Set to
		 ``YES'' to load IPv6 firewall rules at	startup.  If the ker-
		 nel was not built with	options	IPV6FIREWALL, the ip6fw.ko
		 kernel	module will be loaded.

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

     ipv6_firewall_script
		 (str) The IPv6	equivalent of firewall_script.

     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.

     ipv6_firewall_type
		 (str) The IPv6	equivalent of firewall_type.

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

     ipv6_firewall_quiet
		 (bool)	The IPv6 equivalent of firewall_quiet.

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

     ipv6_firewall_logging
		 (bool)	The IPv6 equivalent of firewall_logging.

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

     ipv6_firewall_flags
		 (str) The IPv6	equivalent of firewall_flags.

     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.

     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
		 independently.	 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
		 expected 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(1) network address translation.	See ipfilter_enable
		 for a detailed	discussion.

     ipnat_program
		 (str) Path to ipnat(1)	(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(1) command to execute.

     ipnat_flags
		 (str) Empty by	default.  This variable	contains flags passed
		 to the	ipnat(1) program.

     ipmon_enable
		 (bool)	Set to ``NO'' by default.  Set it to ``YES'' to	enable
		 ipmon(8) monitoring (logging ipf(8) and ipnat(1) 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	exam-
		 ple 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.

     tcp_extensions
		 (bool)	Set to ``YES'' by default.  Setting this to ``NO''
		 disables certain TCP options as described by RFC 1323.	 Set-
		 ting this to ``NO'' might help	remedy such problems with con-
		 nections 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
		 described 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.  This option is only
		 available if the kernel was built with	the TCP_DROP_SYNFIN
		 option.

     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
		 default portrange.  Refer to ip(4) for	more information.

     ip_portrange_last
		 (int) If not set to ``NO'', this is the last port in the
		 default portrange.  Refer to ip(4) for	more information.

     network_interfaces
		 (str) Set to the list of network interfaces to	configure on
		 this host.  For example, if the only network devices in the
		 system	are the	loopback device	(lo0) and a NIC	using the
		 ed(4) driver, this could be set to ``lo0 ed0''.  An
		 ifconfig_<interface> variable is also assumed to exist	for
		 each value of interface.  It is also possible to add IP alias
		 entries here in cases where multiple IP addresses registered
		 against a single interface are	desired.  Assuming that	the
		 interface in question was ed0,	it might look something	like
		 this:

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

		 And so	on.  For each ifconfig_<interface>_alias<n> entry that
		 is found, its contents	are passed to ifconfig(8).  Execution
		 stops at the first unsuccessful access, so if something 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.

		 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.

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

		 ifconfig_ed0="DHCP"

     ipv6_network_interfaces
		 (str) This is the IPv6	equivalent of network_interfaces.
		 Instead of setting the	ifconfig variables as
		 ifconfig_<interface> they should be set as
		 ipv6_ifconfig_<interface>.  Aliases should be set as
		 ipv6_ifconfig_<interface>_alias<n>.  ipv6_prefix_<interface>
		 does something.  Interfaces that do not have a
		 ipv6_ifconfig_<interface> setting will	be auto	configured by
		 rtsol(8) if the ipv6_gateway_enable is	set to ``NO''.	Note
		 that the IPv6 networking code does not	support	the
		 /etc/start_if.<interface> files.

     ipv6_default_interface
		 (str) If not set to ``NO'', this is the default output	inter-
		 face for scoped addresses.  Now this works only for IPv6 link
		 local multicast addresses.

     cloned_interfaces
		 (str) Set to the list of clonable network interfaces to cre-
		 ate on	this host.  Entries in cloned_interfaces are automati-
		 cally appended	to network_interfaces for configuration.

     gif_interfaces
		 (str) Set to the list of gif(4) tunnel	interfaces to config-
		 ure on	this host.  A gifconfig_<interface> variable is
		 assumed to exist for each value of interface.	The value of
		 this variable is used to configure the	link layer of the tun-
		 nel according to the syntax of	the tunnel option to
		 ifconfig(8).  Additionally, this option ensures that each
		 listed	interface is created via the create option to
		 ifconfig(8) before attempting to configure it.

     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_mode	 (str) Mode in which to	run the	ppp(8) daemon.	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 transla-
		 tion.	Used in	conjunction with gateway_enable	allows hosts
		 on private network addresses access to	the Internet using
		 this host as a	network	address	translating router.

     ppp_profile
		 (str) The name	of the profile to use from /etc/ppp/ppp.conf.

     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

     gbde_autoattach_all
		 (bool)	If set to ``YES'', /etc/rc.d/gbde will attempt to
		 automatically initialize your .bde devices in /etc/fstab.

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

     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 ``YES'', the system will 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).

     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
		 automatic mounting at startup by rc(8)	should be delayed
		 until the network is initialized.  It should contain a	white-
		 space-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
		 necessary 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

     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).

     named_rcng	 (bool)	If set to ``YES'' use new functionality	provided in
		 the /etc/rc.d/named script to facilitate a chroot(8) instance
		 of named(8).  This variable is	experimental.  It may be
		 removed or changed in the near	future.

     named_program
		 (str) Path to named(8)	(default /usr/sbin/named).

		 to pass to named(8).

     named_pidfile
		 (str) This is the default path	to the named(8)	daemon's PID
		 file.	Change it if you change	the location in	named.conf(5).

     named_chrootdir
		 (str) The root	directory for a	name server run	in a chroot(8)
		 environment.  If left empty named(8) will not be run in a
		 chroot(8) environment.	 This variable has no effect if
		 named_rcng is not enabled.  This variable is experimental.
		 It may	be removed or changed in the near future.

     named_chroot_autoupdate
		 (bool)	Set to ``NO'' to disable automatic syncing of
		 libraries and other system files between the root file	system
		 and the chroot(8).  This variable has no effect if named_rcng
		 is not	enabled.  This variable	is experimental.  It may be
		 removed or changed in the near	future.

     named_symlink_enable
		 (bool)	Set to ``NO'' to disable symlinking of named_pidfile
		 and /var/run/ndc into the chroot(8) environment in which
		 named(8) is running.  This variable has no effect if
		 named_rcng is not enabled.  This variable is experimental.
		 It may	be removed or changed in the near future.

     kerberos5_server_enable
		 (bool)	Set to ``YES'' to start	a Kerberos 5 authentication
		 server	at boot	time.

     kerberos5_server
		 (str) If kerberos5_server_enable is set to ``YES'' this is
		 the path to Kerberos 5	Authentication Server.

     kadmind5_server_enable
		 (bool)	Set to ``YES'' to start	kadmind(8), the	Kerberos 5
		 Administration	Daemon;	set to ``NO'' on a slave server.

     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

     mountd_enable
		 (bool)	If set to ``YES'', and no nfs_server_enable is set,
		 start mountd(8), but not nfsd(8) daemon.  It is commonly

		 the display and functionality of function key labels (as
		 found on Hewlett-Packard terminals such as the	HP2392A	and
		 the HP700/92 in ANSI mode).

     pcvt_lines	 (int) Set to ``NO'' by	default	resulting in a value of	25.
		 Used to set the number	of lines on the	screen.	 For VGA dis-
		 plays,	valid values are 25, 28, 40 and	50 lines.  (See	also
		 the scon(1) manual page.)

     pcvt_blanktime
		 (int) Set to ``NO'' by	default.  Used to set the screen saver
		 timeout in seconds for	values greater than zero.

     pcvt_cursorh
		 (int) Set to ``NO'' by	default.  Used to set the cursor top
		 scanline.  (See also the cursor(1) manual page.)

		 (int) Set to ``NO'' by	default.  Used to set the cursor bot-
		 tom scanline.

     pcvt_monohigh
		 (bool)	Set to ``NO'' by default.  Set to ``YES'' to set

		 entropy source.  Refer	to random(4) for more information.

     harvest_ethernet
		 (bool)	Set to ``YES'' to use LAN traffic as an	entropy
		 source.  Refer	to random(4) for more information.

     harvest_p_to_p
		 (bool)	Set to ``YES'' to use serial line traffic as an
		 entropy source.  Refer	to random(4) for more information.

     entropy_dir
		 (str) Set to ``NO'' to	disable	caching	entropy	via cron(8).
		 Otherwise set to the directory	used to	store entropy files
		 in.

     entropy_file
		 (str) Set to ``NO'' to	disable	caching	entropy	through
		 reboots.  Otherwise set to the	filename used to store cached
		 entropy through reboots.  This	file should be located on the
		 root file system to seed the random(4)	device as early	as
		 possible in the boot process.

     entropy_save_sz
		 (int) Size of the entropy cache files saved by	save-entropy
		 periodically.
