Hi Yanis,

I think that better systemd management should be available. However, I
think that it should be provided via a specific systemd native type instead
of service.

The systemd native type can use autonotify to prod the associated service
on restart.

My reasoning here is that the service type collects a specific, common, set
of functionality across all service providers. What you are indentifying is
the configuration file portion of a particular service. If you attempted to
provide all of these options for everything in init, upstart, and systemd
(and others!) in the 'service' type, it would become insanely cluttered and
complex.

Thanks,

Trevor
