systemd --user is now always started as a service by PID1, triggered by logind.

$ tree -d /sys/fs/cgroup/systemd/user.slice/
/sys/fs/cgroup/systemd/user.slice/
`-- user-2702.slice
    |-- session-1.scope
    `-- user at 2702.service

You need to chown() the cgroup subtree yourself if you start your own
systemd --user.

It all needs still some work how things should work in the end, we are
not quite there to offer a fully working default setup of systemd
--user.
