brc(1M)                                                             brc(1M)

NAME
     brc, bcheckrc - system initialization procedures

SYNOPSIS
     /etc/brc

     /sbin/bcheckrc

DESCRIPTION
     These shell procedures are executed via entries in /etc/inittab by
     init whenever the system is booted.

     The brc script performs operations necessary to initialize the I/O
     subsystem and the virtual disks. A verbose mode also prints out the
     current hardware system configuration.

     First, the bcheckrc procedure checks the status of the root file sys-
     tem. If the root file system is found to be bad, bcheckrc repairs it.

     Then, bckeckrc mounts the /stand, /proc, and /var (if it exists) file
     systems (/var may exist as a directory in the root file system, or as
     a separate file system).

     When these two procedures have been executed, init checks for the
     initdefault value in /etc/inittab. This tells init in which run level
     to place the system. If, for example, initdefault is set to 2, the
     system will be placed in the multiuser state via the rc2 procedure.

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