6.77.2. Contents of Sysvinit

Installed programs: bootlogd, fstab-decode, halt, init, killall5, poweroff (link to halt), reboot (link to halt), runlevel, shutdown, and telinit (link to init)

Short Descriptions

bootlogd

Logs boot messages to a log file

fstab-decode

Run a command with fstab-encoded arguments

halt

Normally invokes shutdown with the -h option, except when already in run-level 0, then it tells the kernel to halt the system; it notes in the file /var/log/wtmp that the system is being brought down

init

The first process to be started when the kernel has initialized the hardware which takes over the boot process and starts all the proceses specified in its configuration file

killall5

Sends a signal to all processes, except the processes in its own session so it will not kill its parent shell

poweroff

Tells the kernel to halt the system and switch off the computer (see halt)

reboot

Tells the kernel to reboot the system (see halt)

runlevel

Reports the previous and the current run-level, as noted in the last run-level record in /var/run/utmp

shutdown

Brings the system down in a secure way, signaling all processes and notifying all logged-in users

telinit

Tells init which run-level to change to
