.TH RC 8
.CT 1 sa_auto
.SH NAME
rc \- boot script
.SH SYNOPSIS
.B /etc/rc
.SH DESCRIPTION
.I Rc
is the command script
invoked by
.IR init (8)
to control reboots.
During an automatic reboot,
.I rc
is invoked with the argument
.BR autoboot ;
typically this invokes
.L /etc/fsck -p
to repair minor filesystem inconsistencies.
If
.I rc
exits with a successful status,
.I init
proceeds to multi-user mode.
.PP
When the system enters multi-user mode,
either during an auto-reboot
or after the single-user shell terminates,
.I rc
is invoked without arguments.
This usually causes it to
mount filesystems,
start daemons,
clear
.FR /tmp ,
and perform other housekeeping.
.PP
If any call to
.I rc
returns a nonzero status,
.I init
reverts to single-user mode.
.SH EXAMPLES
A typical
.I rc
script:
.PP
