The listed service file simply uses ths existing SysV init script via ExecStart, ExecStop, etc.
The main logic of more complex init scripts should be moved into helper scripts which can be used directly from both the .service file and the init script. This will also make the init scripts more readable and easier to support other alternatives. Note that as /etc/init.d/* files are conffiles, such updates are not guaranteed to reach users.
