for a important kernel-update I need to reboot the linux-boxes today. The
reboot will happen
TODAY, 20:00 UTC.
The linux userland-boxes will be away for ~10min and the database-servers
(sql-s2 and sql-s2) for 30min (all values are estimates). Solaris-boxes are
not affected. The reboots will happen sequentially so SGE should re-schedule
tasks between the boxes so the downtime for each task should be short.
