Why do you need a pidfile? When I get systemd to start a process, I
just have it not fork. Much easier. Forget about python-daemon - just
run your script in the simple and straight-forward way.
(Possibly that'll mean having it do different things depending on
whether it's started from systemd or some other way, but that can be
controlled with a parameter.)
