brc(1M)               UNIX System V(Essential Utilities)                brc(1M)


NAME
      brc, bcheckrc - system initialization procedures

SYNOPSIS
      /sbin/brc

      /sbin/bcheckrc

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

      First, the bcheckrc procedure checks the status of the root file system.
      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).

      The brc script performs administrative tasks related to file sharing.

      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.  If, for example, initdefault is set to 2, the system will be
      placed in the multi-user 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.
