bcheckrc(ADM)

Syntax

Description

When the system autoboots, init calls bcheckrc with the -a option so that bcheckrc will run without operator intervention.

The main actions performed by bcheckrc are:

• If the system has not autobooted, run dumpsave(ADM) to allow a system memory image (kernel panic dump) to be copied from the swap area to floppy disk or tape

• Check the status of the root and boot filesystems and repair these, if necessary, using fsck(ADM)

• Clear the mounted filesystem table, /etc/mnttab, put the entry for the root filesystem into the mount table, and mount the boot filesystem using btmnt(ADM)

• Start the system logger daemon, syslogd(ADM)

After running bcheckrc, 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 will be placed in the multiuser state via the /etc/rc2 procedure.

bcheckrc may be used for several run-level states.
