- Configuration of System V init under Debian GNU/Linux
-
- Most Unix versions have a file here that describes how the scripts
- in this directory work, and how the links in the /etc/rc?.d/ directories
- influence system startup/shutdown.
-
- For Debian, this information is contained in the policy manual, chapter
- "System run levels and init.d scripts". The Debian Policy Manual is
- available at:
-
- http://www.debian.org/doc/debian-policy/#contents
-
- 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.
-
- All init.d scripts are expected to have a LSB style header documenting
- dependencies and default runlevel settings. The header look like this
- (not all fields are required):
-
- ### BEGIN INIT INFO
- # Provides: skeleton
- # Required-Start: $remote_fs $syslog
- # Required-Stop: $remote_fs $syslog
- # Should-Start: $portmap
- # Should-Stop: $portmap
- # X-Start-Before: nis
- # X-Stop-After: nis
- # Default-Start: 2 3 4 5
- # Default-Stop: 0 1 6
- # X-Interactive: true
- # Short-Description: Example initscript
- # Description: This file should be used to construct scripts to be
- # placed in /etc/init.d.
- ### END INIT INFO
-
- More information on the format is available from insserv(8). This
- information is used to dynamicaly assign sequence numbers to the
- boot scripts and to run the scripts in parallel during the boot.
- See also /usr/share/doc/insserv/README.Debian.
