brc(1M)								       brc(1M)

NAME    [Toc]    [Back]

     brc, bcheckrc - system initialization procedures

SYNOPSIS    [Toc]    [Back]

     /etc/brc
     /etc/bcheckrc

DESCRIPTION    [Toc]    [Back]

     These shell procedures are	executed via entries in	/etc/inittab by
     init(1M) whenever the system is booted (or	rebooted).

     First, the	bcheckrc procedure checks the status of	the root filesystem.
     If	the root filesystem is found to	be bad,	bcheckrc repairs it.

     Then, the brc procedure clears the	mounted	filesystem table, /etc/mtab,
     and puts the entry	for the	root filesystem	into the mount table.

     After these two procedures	have executed, init checks for the initdefault
     value in /etc/inittab.  This tells	init in	which run level	to place the
     system.  Since initdefault	is initially set to 2, the system is placed in
     the multiuser state via the /etc/rc2 procedure.

     Note that bcheckrc	should always be executed before brc.  Also, these
     shell procedures can be used for several run-level	states.
