brc(1M)

brc, bcheckrc -- system initialization procedures

Synopsis

/sbin/brc

/sbin/bcheckrc

Description

The bcheckrc procedure first checks the status of the root file system. If the root file system is found to be bad, bcheckrc repairs it. Then, it mounts the /stand, /proc, /dev/_tcp, and /var (if it exists) file systems (/var may exist as a directory in the root file system, or as a separate file system). bcheckrc is executed by an entry in /etc/inittab by init whenever the system is booted.

The brc script performs administrative tasks related to file sharing. The functionality of brc has been incorporated into other startup routines, and is no longer executed by /etc/inittab. It is kept for compatibility reasons.

After bcheckrc has 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.
