.Sh NAME
.Nm rc
.Nd command script for auto\-reboot and daemons
.Nd command scripts for auto\-reboot and daemon startup
.Sh SYNOPSIS
.Nm rc
.Nm rc.conf
.Nm rc.conf.local
.Nm rc.serial
.Nm rc.pccard
.Nm rc.network
.Nm rc.firewall
.Nm rc.<arch>
.Nm rc.local
.Nm rc.shutdown
.Sh DESCRIPTION
.Nm Rc
is the command script which controls the automatic reboot and
is the command script which controls the automatic reboot
(calling the other scripts) and
.Nm rc.local
is the script holding commands which are pertinent only
to a specific site.
.Nm Rc.conf
contains the global system configuration information referenced
by the rc files, while
.Nm rc.conf.local
contains the local system configuration.
.Pp
.Nm Rc.shutdown
is the command script which contains any necessary commands
to be executed as the system is shut down.
.Pp
When an automatic reboot is in progress,
.Nm rc
@ -75,28 +93,56 @@ starts all the daemons on the system, preserves editor files
and clears the scratch directory
.Pa /tmp .
.Pp
.Nm Rc.local
is executed immediately before any other commands after a successful
.Nm fsck .
Normally, the first commands placed in the
.Nm rc.local
file define the machine's name, using
.Xr hostname 1 ,
and save any possible core image that might have been
generated as a result of a system crash, with
.Xr savecore 8 .
The latter command is included in the
.Nm rc.local
file because the directory in which core dumps are saved
is usually site specific.
.Nm Rc.serial
is used to set any special configurations for serial devices.
.Pp
Following tradition, the startup files
.Nm Rc.pccard
is used to enable PC-cards.
.Pp
.Nm Rc.network
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.
.Pp
.Nm Rc.firewall
is used to configure rules for the kernel based firewall
service. It has several possible options:
.Pp
.Bl -tag -width "fBfilename" -compact -offset indent
.It open
will allow anyone in.
.It client
will try to protect just this machine.
.It simple
will try to protect a whole network.
.It closed
totally disables IP services except via lo0 interface.
.It UNKNOWN
disables the loading of firewall rules.
.It filename
will load the rules in the given filename (full path required).
.El
.Pp
.Nm Rc.<arch>
runs architecture specific programs.
.Pp
.Nm Rc.local
is executed after the scripts above, but before the rest of the
.Nm rc
and
file is completed.
Presently, all
.Nm rc.local
reside in
does is to put version information in
.Pa /etc/motd .
.Pp
Following tradition, the startup files reside in
.Pa /etc .
