I'm a downstream as well (Debian), which was caught by this change.
Note this particular change was merged after the official beta release
and is only in Git atm, but it's targetted for 3.22.
Personally I'm a bit concerned that such a far reaching change was
slipped in *after* the beta release.

If you look at 770758, where I tried to make gnome-user-share
buildable on on-systemd systems, this bug was rejected, on the grounds
that g-s-d now requires systemd --user to start those services.

The implications I see so far are:
- gnome-user-share is no longer buildable on non-systemd systems
- vino is no longer buildable on non-systemd systems
- the sharing panel in g-c-c will be broken as it requires g-s-d
sharing which no relies on systemd --user.

Now, logind, timedated, hostnamed and localed are something completely
different. Those are system services, where writing a replacement at
least for the latter 3, is rather simple.

systemd --user is much more involved. Providing a replacement for that
is imho, not easily possible.

Michael
