DESCRIPTION
Generic init.d script framework to reduce the redundant code in /etc/init.d/. The goal is to create an init.d script that is Debian and LSB compliant. When the Debian policy conflict with the LSB, the Debian policy take preference. See The LSB specification <http://refspecs.linuxfoundation.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html> for information about init.d scripts in the LSB.This is a simple example on how init-d-script can be used to start and stop a daemon with PID file support:
-
#!/lib/init/init-d-script ### BEGIN INIT INFO # Provides: atd # Required-Start: $syslog $time $remote_fs # Required-Stop: $syslog $time $remote_fs # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: run at jobs # Description: Debian init script to start the daemon # running at jobs. ### END INIT INFO DAEMON=/usr/sbin/atd
In addition to the DAEMON setting, one can specify DESC, NAME, PIDFILE (none means no PID file), or implement override functions do_force_reload_override, do_reload_override, do_restart_override, do_start_override, do_start_cmd_override, do_start_prepare, do_start_cleanup do_status_override, do_stop_override, do_stop_prepare, do_stop_cleanup and do_stop_cmd_override.
If the daemon support reloading, implement the do_reload function to make the init.d script recognize the reload operation as well as use it for the force-reload operation.
If DAEMON is 'none', the check to see if the daemon is installed is disabled, and replacement functions do_start_cmd_override, do_stop_cmd_override and do_status_override functions must be implemented.
Services supporting reload should define the do_reload function. If the service handle reload using a SIGUSR1 signal, the following alias can be used instead of implementing ones own do_reload function:
-
alias do_reload=do_reload_sigusr1
