==Introduction==

''/etc/rc.conf'' 

The global [[OpenRC]] configuration file.<br/>

==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 [https://www.freebsd.org/cgi/man.cgi?query=rc.conf&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html '''rc.conf(5)'''] 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 administrator wishes	to override these defaults.  The file '''/etc/rc.conf.local''' is used to override settings in '''/etc/rc.conf''' for historical reasons.

The [https://www.freebsd.org/cgi/man.cgi?query=sysrc&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sysrc(8)] command provides a scripting interface to modify system config files.

In	addition to '''/etc/rc.conf.local''' you can also place smaller configuration files	for each [https://www.freebsd.org/cgi/man.cgi?query=rc&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports rc(8)] script in the '''/etc/rc.conf.d''' directory.

==Example==

The command <code> cat /etc/rc.conf</code> will show you somthing like this:

{|class="wikitable" style="width:96.5%;background:#FFFFFF; border:2px solid #008000;text-align:left;padding: 10px" 
|-
! scope="col" style="width: 100px;"|'''Name'''
! scope="col" style="width: 350px;"|'''Description'''
|-
|root_rw_mount="NO"||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''.
|-
|sendmail_enable="NONE"||If set to "YES", run	the [https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)]	daemon at system boot  time.  If set to "NO", do not run a [https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)] daemon to listen   for incoming network mail.	 This does not preclude	a [https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)]    daemon listening on the SMTP port of the loopback interface.  The     "NONE" option is deprecated and should not	be used.  It will be    removed in	a future release.
|-
|sendmail_submit_enable="NO"||If set to "YES" and	sendmail_enable	is set to "NO",	run [https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)] using sendmail_submit_flags instead of  sendmail_flags.  This is intended to allow	local mail submission   via a localhost-only listening SMTP service required for running     [https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)] as a non-set-user-ID binary.  Note that this does not     work inside [https://www.freebsd.org/cgi/man.cgi?query=jail&sektion=2&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports jail(2)] systems, as jails do not allow	binding	to     just the localhost	interface.

|-
|sendmail_outbound_enable="NO"||If set to "YES" and	both sendmail_enable and    sendmail_submit_enable are	set to "NO", run [[https://www.freebsd.org/cgi/man.cgi?query=sendmail&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports sendmail(8)] using     sendmail_outbound_flags instead of	sendmail_flags.	 This is intended to allow local mail	queue management for systems that do    not offer a listening SMTP	service.

|-
|sendmail_msp_queue_enable="NO"||If set to "YES", start a client (MSP) queue	runner    sendmail(8) daemon	at system boot time.  As of sendmail 8.12, a    separate queue is used for	command	line submissions.  The client     queue runner ensures that nothing is left behind in the submission queue.
|-
|devfs_system_ruleset="devfsrules_common"||Rule name(s) to apply to	the system ''/dev'' itself.
|-
|kld_list="linux linux64 cuse"||kld_list: 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.
|-
|ntpd_sync_on_start="YES"||If set to "YES", [https://www.freebsd.org/cgi/man.cgi?query=ntpd&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports ntpd(8)] is run	with the -g flag, which syncs the system's clock	on startup.  See [https://www.freebsd.org/cgi/man.cgi?query=ntpd&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports ntpd(8)] for  more information regarding the	-g option.  This is a preferred	alternative to using [https://www.freebsd.org/cgi/man.cgi?query=ntpdate&sektion=8&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports ntpdate(8)]	or specifying the 	'' ntpdate_enable	''variable.
