I think this is a consequence of another bug (Psystem_daemon() was
failing to detect that systemd was running correctly on systemd v2
systems, and we were falling back to the old approach, which is indeed
going to conclude that processes in system groups without controlling
terminals or associated TTYs are system daemons).

I have a fix for this detection failure under test now and will post it
shortly.
