Description of problem:
systemd waits 2 minutes for a usermanager to end, which never was running
It's noticeable on reboots, when the timer for the "no longer loggedin" usersession counts to two minutes.
I think it a bug in systemd to not recognize, that the sessions already ended.
Due to the nature of this bug, screenshoting it may only work in VMs.
