Short Descriptions

checkfs

Checks the integrity of the file systems before they are mounted (with the exception of journal and network based file systems)

cleanfs

Removes files that should not be preserved between reboots, such as those in /var/run/ and /var/lock/; it re-creates /var/run/utmp and removes the possibly present /etc/nologin, /fastboot, and /forcefsck files

console

Loads the correct keymap table for the desired keyboard layout; it also sets the screen font

functions

Contains common functions, such as error and status checking, that are used by several bootscripts

halt

Halts the system

ifdown

Assists the network script with stopping network devices

ifup

Assists the network script with starting network devices

localnet

mountfs

mountkernfs

Mounts virtual kernel file systems, such as proc

network

reboot

Reboots the system

sendsignals

Makes sure every process is terminated before the system reboots or halts

setclock

Resets the kernel clock to local time in case the hardware clock is not set to UTC time

static
