Note that user at .service actually can be made to stay around if user
lingering is on (see loginctl enable-linger). The idea here is that
allowing cronjobs and suchlike of the user while the user isn't actually
logged in must be something that is explicitly enabled. And the the
lingerng stuff is supposed to do that.
