Yes and no. The normal service handling should make sure that normal services should not be around anymore when this code is invoked. However, there's stuff that's not exactly "normal services". Most prominently user sessions. To cover those I plan to add a service that kills all user sessions on shutdown very early, i.e. before we kill all the services. That's something that has been missing in sysv for quite a while and we now can add that here for the first time. And then there's everything that moves itself to a different cgroup in the systemd hierarchy. Which privileged code might do.
