pstree is not quite unequivocal, because it shows systemd at the top of
every running process, even those surely not started by systemd but e.g. by
the current user.

But on the other hand systemd has PID 1 so it's reasonable to assume
everything stems from it.

Although when I do lsof |grep rsys |grep syst it returns nothing, so
perhaps that means rsyslog was not started by systemd: we'd have to compare
with a system where systemctl status rsyslog.service gives a better result.

"lsof |grep cgrou" returns only one line:

systemd       1             root    6r      DIR               0,18
0        193 /sys/fs/cgroup/systemd/system

I hope this gives some clues.
