Scripts Executed Indirectly by init
These are run when changing the runlevel and always call the master script
/etc/init.d/rc, which guarantees the correct order of the relevant scripts.
All scripts are located in /etc/init.d. Scripts that are run at boot time are called
through symbolic links from /etc/init.d/boot.d. Scripts for changing the run-
level are called through symbolic links from one of the subdirectories (/etc/init
.d/rc0.d to /etc/init.d/rc6.d). This is just for reasons of clarity and avoids
duplicate scripts if they are used in several runlevels. Because every script can be exe-
cuted as both a start and a stop script, these scripts must understand the parameters
start and stop. The scripts also understand the restart, reload,
force-reload, and status options. These different options are explained in
ble 7.2, "Possible init Script Options"
not have these links. They are run independently from the runlevel when needed.

Links in each runlevel-specific subdirectory make it possible to associate scripts with
different runlevels. When installing or uninstalling packages, these links are added and
removed with the help of the program insserv (or using /usr/lib/lsb/install
_initd, which is a script calling this program). See the insserv(8) man page for details.
