RC.CONF(8)		FreeBSD	System Manager's Manual		    RC.CONF(8)

NAME
     rc.conf, rc.conf.local -- system daemon configuration database

DESCRIPTION
     The file rc.conf contains a series	of variable assignments	that are used
     to	configure the system daemons.  These variables are read	by rc(8) early
     on	in the boot sequence and every time an rc.d(8) script is executed.

     It	is advisable to	leave rc.conf untouched, and instead create and	edit a
     new rc.conf.local file or use the rcctl(8)	utility.  Since	only the last
     assignment	to any variable	takes effect, variables	set in this file over-
     ride variables previously set in rc.conf.

     rc.conf is	made up	of variable assignments	(variable=value) with comments
     designated	by a hash mark (`#').

     Base system daemon	configuration variables	are used to enable and disable
     daemon programs that are installed	by default, and	to set their command
     line options.

     All of these variables follow the format "daemon_flags" where daemon is
     the name of one of	the rc.d(8) daemon control scripts.  The list of base
     system daemons, including the information whether they are	enabled	by de-
     fault, can	be displayed with this command:

	   grep	_flags /etc/rc.conf

     If	one of these variables is set to NO, the respective daemon is dis-
     abled.  If	set to the empty string, the daemon is run with	the default
     command line arguments defined in its rc.d(8) daemon script, or without
     command line arguments if no such default exists.	If set to any other
     value, including a	string containing only a single	blank character, the
     daemon is run with	those command line arguments.

     Package daemon configuration variables are	used to	enable and disable
     daemon programs installed from packages(7), and to	set their command line
     options.

     The special pkg_scripts variable lists rc.d(8) daemon control scripts to
     be	started	in the specified order.	 For each daemon listed, its default
     command line options can optionally be overridden using the variable
     daemon_flags as described above.

     Base system service configuration variables control features available by
     default that are not implemented as daemons.  They	can be set to either
     YES or NO.	 When set to YES, they have the	following effects:

     accounting	   rc calls: accton(8) /var/account/acct

     check_quotas  rc calls: quotacheck(8) -a; quotaon(8) -a

     ipsec	   rc calls: ipsecctl(8) -f /etc/ipsec.conf

     library_aslr  rc reorders some libraries for improved protection against
		   ROP.

     multicast	   See multicast(4).

     pf		   rc calls: pfctl(8) -ef /etc/pf.conf

     spamd_black   The script /etc/rc.d/spamd uses -b in front of any other
		   configured command line arguments when running spamd(8) and
		   spamd-setup(8).

     Auxiliary configuration variables mostly determine	the locations of spe-
     cific configuration files.	 The boot scripts use them as follows:

     amd_master	 The amd(8) master map file.  The script /etc/rc.d/amd appends
		 its content to	the command line when starting the auto
		 mounter daemon.

     shlib_dirs	 Extra shared library search path entries.  rc calls:
		 ldconfig(8) /usr/X11R6/lib /usr/local/lib ${shlib_dirs}

EXAMPLES
     Do	not start the dhcpd(8) daemon when booting the system:

	   dhcpd_flags=NO

     To	run the	dhcpd daemon, add the following	line to	rc.conf.local:

	   dhcpd_flags=

     To	start it with some options:

	   dhcpd_flags=-A abandoned

     Run /etc/rc.d/messagebus then /etc/rc.d/cupsd with	the start argument at
     boot time,	and in reverse order with the stop argument at shutdown:

	   pkg_scripts=messagebus cupsd

     The default location of the amd(8)	master map file	is:

	   amd_master=/etc/amd/master	   # AMD 'master' map
