Bug#692539: debian-edu-config: Diskless workstations with XFCE do not register logged in users in utmp

[Petter Reinholdtsen <pere@hungry.com>]

Package: debian-edu-config
Version: 1.453
Severity: important

A customer reported that shutdown-at-night on diskless workstations
running XFCE turn off machines even if there is a user logged in.  The
cause is that the logged in user is not registered in utmp, causing
'who' to not show any logged in users, making shutdown-at-night to
believe the machine is unused.

I am not quite sure why, but one idea might be that /var/lib/kdm is used
to store the current user status, and the fact that this directory isn't
writable causes kdm to not update utmp.  If that is the case, this patch
should solve it.

I have not been able to test if this solution work, but mention it here
in case any one have time to test it.
