2008-03-18: Update of all user accessible SL5 systems to release 5.1

Tonight, all SL5 desktops will receive the minor update to SL5.1. This is a normal procedure happening about twice a year. SL5 farm nodes and most WGS have been updated last night already.

We don't expect any problems due to this update. There is no need to reboot any systems.
