rc(1M)                                                     rc(1M)



NAME
     rc, bcheckrc, powerfail, rc.boot, rc.single - system ini-
     tialization shell scripts

SYNOPSIS
     /etc/bcheckrc

     /etc/rc

     /etc/rc.boot

     /etc/rc.single

     /etc/powerfail

DESCRIPTION
     These shell procedures are executed via entries in
     /etc/inittab by init(1M).

     The rc.boot procedure is executed before entering single or
     multi-user modes. It will run fsck(1M) on the root file sys-
     tem. It will then run the rc.single script if the fsck was
     successful.

     The rc.single procedure remounts the root file system read-
     write, then clears the mounted file system table, /etc/mtab
     (see mtab(4)).  The rc.single procedure is automatically
     invoked by rc.boot (if the fsck is successful) and by rc (if
     rc.single has not previously been run).  rc.single can be
     invoked manually if write access is required on the root
     file system after a failure of rc.boot.

     The bcheckrc procedure performs all the necessary con-
     sistency checks to prepare the system to change into multi-
     user mode.  It will check the file systems with fsck(1M).
     It is invoked from inittab prior to going into multi-user
     mode.

     The rc procedure starts all system daemons before the termi-
     nal lines are enabled for multi-user mode.  In addition,
     file systems are mounted and accounting, error logging, sys-
     tem activity logging and the Remote Job Entry (RJE) system
     are activated in this procedure.

     The powerfail procedure is invoked when the system detects a
     power failure condition.  Its chief duty is to reload any
     programmable micro-processors with their appropriate
     scripts, if suitable.  It also logs the fact that a power
     failure occurred.
