The script boot is also responsible for starting all the scripts in /etc/init.d/
boot.d with a name that starts with S. There, the file systems are checked and
loop devices are configured if needed. The system time is also set. If an error occurs
while automatically checking and repairing the file system, the system administrator
can intervene after first entering the root password. Last executed is the script
boot.local.
boot.local
Here, enter additional commands to execute at boot before changing into a runlevel.
It can be compared to AUTOEXEC.BAT on DOS systems.
boot.setup
This script is executed when changing from single user mode to any other runlevel
and is responsible for a number of basic settings, such as the keyboard layout and
initialization of the virtual consoles.
halt
This script is only executed while changing into runlevel 0 or 6. Here, it is executed
either as halt or as reboot. Whether the system shuts down or reboots depends
on how halt is called.
rc
This script calls the appropriate stop scripts of the current runlevel and the start
scripts of the newly selected runlevel.
You can create your own scripts and easily integrate them into the scheme described
above. For instructions about formatting, naming, and organizing custom scripts, refer
to the specifications of the LSB and to the man pages of init, init.d, chkconfig,
and insserv. Additionally consult the man pages of startproc and killproc.
WARNING: Faulty init Scripts May Halt Your System
Faulty init scripts may hang your machine. Edit such scripts with great care and,
if possible, subject them to heavy testing in the multiuser environment. Find
some useful information about init scripts in
(page 393).
To create a custom init script for a given program or service, use the file /etc/init
.d/skeleton as a template. Save a copy of this file under the new name and edit
the relevant program and filenames, paths, and other details as needed. You may also
