cron maybe used for shutdown-at-night.

As far as I know, these are running on diskless workstations only.
(If connected to the 192.168.x.x network, a client with enough RAM is
running as diskless workstation per default.)

I guess, yes:
This is the 'pstree' output on a thin client if a user is logged in:

And this, if only the login screen is shown.
