NAME
rc —
command script for auto-reboot and
daemons
SYNOPSIS
rc |
rc.local |
DESCRIPTION
Rc is the command script which controls the automatic
reboot and rc.local is the script holding commands
which are pertinent only to a specific site.
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.local is executed immediately before
any other commands after a successful
fsck. Normally, the first
commands placed in the rc.local file define the
machine's name, using
hostname(1), and save any possible core image that might have been
generated as a result of a system crash, with
savecore(8). The latter command is included in the
rc.local file because the directory in which core
dumps are saved is usually site specific.
Following tradition, the startup files rc
and rc.local reside in
/etc.
