If this is a sysv init script then systemd will start this service
anyway, no need to write a unit file like the above. systemd provides a
certain level of compatibility with sysv scripts.

Too late? What do you mean by that?

Hmm, the idea here is that a systemd service is started at bootup, and
stopped at shutdown. This output looks like you start and stop it at shutdown.

Well, for that you actually have to explain after what and before what
other services you want your service to be terminated.
