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

     rc - command scripts for auto-reboot and daemon startup


     Rc is the command script which controls the automatic reboot (calling the
     other scripts) and rc.local is the script holding commands which are
     pertinent only to a specific site.  Typically, the /usr/local/etc/rc.d
     mechanism is used instead of rc.local these days but if you do want to
     use rc.local, /etc/rc still supports it.  In this case, rc.local should
     source /etc/rc.conf and contain additional custom startup code for your
     system.  Rc.conf contains the global system configuration information
     referenced by the rc files, while rc.conf.local contains the local system
     configuration.  See rc.conf(5)

     Rc.shutdown is the command script which contains any necessary commands
     to be executed as the system is shut down.

     When an automatic reboot is in progress, rc is invoked with the argument
     autoboot.  The first portion of rc runs an fsck(8) with option -p to
     ``preen'' all the disks of minor inconsistencies resulting from the last
     system shutdown and to check for serious inconsistencies caused by
     hardware or software failure.  If this auto-check and repair succeeds,
     then the second part of rc is run.

     The second part of rc, which is run after an auto-reboot succeeds and
     also if rc is invoked when a single user shell terminates (see init(8)),
     starts all the daemons on the system, preserves editor files and clears
     the scratch directory /tmp.

     Rc.serial is used to set any special configurations for serial devices.

     Rc.pccard is used to enable PC-cards. is used to start the network.  The network is started in three
     passes.  The first pass sets the hostname and domainname, configures the
     network interfaces, turns on any IP firewall rules, and starts routing.
     The second pass starts most of the network related daemons.  The third
     pass starts NFS, amd, rwhod, Kerberos and the multicast routing daemon.

     Rc.firewall is used to configure rules for the kernel based firewall
     service.  It has several possible options:

           open        will allow anyone in.
           client      will try to protect just this machine.
           simple      will try to protect a whole network.
           closed      totally disables IP services except via lo0 interface.
           UNKNOWN     disables the loading of firewall rules.
           filename    will load the rules in the given filename (full path

     Rc.atm is used to configure ATM network interfaces.  The interfaces are
     configured in three passes.  The first pass performs the initial
     interface configuration.  The second pass completes the interface
     configuration and defines PVCs and permanent ATMARP entries.  The third
     pass starts any ATM daemons.

     Rc.<arch> runs architecture specific programs.

     Rc.local is executed after the scripts above, but before the rest of the
     rc file is completed.  Presently, all rc.local does is to put version
     information in /etc/motd.

     Following tradition, the startup files reside in /etc.

     rc.conf(5), init(8), reboot(8), savecore(8)

     The rc command appeared in 4.0BSD.
