The programs in question are interaktive programs (like an editor),
which are called by different users several times in parallel with
parameters they want.
(The programs attach to the supervisor process via shared memory)

I'm new to systemd, but I don't think I can write units for this.

But if systemd kills these processes first with a SIGTERM and only
after some time with SIGKILL, I could catch SIGTERM and can orderly
terminate the processes. This would solve our problem.

I assume systemd does it this way, right?
