Uit de readme file The scripts in this directory are executed each time the system enters
this runlevel.
The scripts are all symbolic links whose targets are located in
/etc/init.d/ .
To disable a service in this runlevel, rename its script in this
directory so that the new name begins with a 'K' and a two-digit
number, and run 'update-rc.d script defaults' to reorder the scripts
according to dependencies. A warning about the current runlevels
being enabled not matching the LSB header in the init.d script will be
printed. To re-enable the service, rename the script back to its
original name beginning with 'S' and run update-rc.d again.
For a more information see /etc/init.d/README.
The Debian Policy Manual is also available in the Debian package
"debian-policy". When this package is installed, the policy manual can be
found in directory /usr/share/doc/debian-policy. If you have a browser
installed you can probably read it at
file://localhost/usr/share/doc/debian-policy/
Some more detailed information can also be found in the files in the
/usr/share/doc/sysv-rc directory.
Debian Policy dictates that /etc/init.d/*.sh scripts must work properly
when sourced. The following additional rules apply:
* /etc/init.d/*.sh scripts must not rely for their correct functioning
on their being sourced rather than executed. That is, they must work
properly when executed too. They must include "#!/bin/sh" at the top.
This is useful when running scripts in parallel.
* /etc/init.d/*.sh scripts must conform to the rules for sh scripts as
spelled out in the Debian policy section entitled "Scripts" (§10.4).
Use the update-rc.d command to create symbolic links in the /etc/rc?.d
as appropriate. See that man page for more details.
