Service Wrapper Scripts

If your service requires to run additional commands, executed before the service is actually started, like the systemd ExecStartPre, you can use a wrapper shell script to start your service.

The Finit service .conf file can be put into /etc/finit.d/available, so you can control the service using initctl. Then use the path to the wrapper script in the Finit .conf service block. The following example employs a wrapper script in /etc/start.d.

Example:

• /etc/finit.d/available/program.conf:

  service program {
      description   = "Example Program"
      runlevel      = "235"
      reload-signal = "none"
      command       = "/etc/start.d/program"
  }
  

• /etc/start.d/program:

  #!/bin/sh
  # Prepare the command line options
  OPTIONS="-u $(cat /etc/username)"
  
  # Execute the program
  exec /usr/bin/program $OPTIONS
  

Note

The example sets reload-signal = "none" to say the program does not support SIGHUP. Finit then stop/starts the service instead of signalling it at restart/reload events.
