But it is just another method of starting D-Bus. It is still started
as part of standard startup (i.e. Fedora installs
/lib/systemd/system/multi-user.target.wants/dbus.service) and should
be stopped when multi-user.target is stopped as well. There is no
magic in handling SPECIAL_DBUS_SERVICE except attempting to reconnect
to it when it is started.

So may be it changes timing so this problem becomes less obvious, but
I do not see how it fixes it.

I myself never experienced problems on shutdown due to d-bus (which
seems to hint  this is a timing issue). Eugeni, could you get debug
output to console up to the moment shutdown hangs? I used
systemd.log_target=kmsg, systemd.log_level=debug and set LOGLEVEL=8 in
/etc/sysconfig/init so that everything is dumped on console.
