Comment 26 for bug 1901582

Oh, interesting. So we have 3 options:

GetSessionByPid -> then get the seat
Seat/self
Seat/auto

GetSessionFromPid works in old systemd but broke in newer versions
self fails in some situations
auto is only available in new systemd

I assumed if auto didn't work I could just leave it on the old path... seemingly that is not the case.
