=== ZFS update issues ===
ZFS not part of kernel. When using kdms, a manual rebuild action is required. When using kmod this should work more smoothly. Before the stopday: Test an update a CentOS hypervisor (wop61)

=== Matplotlib update ===

The Matplotlib update was postponed (not well tested). Was updated later (20-11-2018)

=== Stop virtualbox ===

Virtualbox should be stopped on alta2 before updates start

=== GPG keys  ===
All GPG keys should be in place before updates start (Ubuntu)

=== Test spare LCU ===
Lcu-rt0 became lcu-rt6. Several adjustments needed (casacore,pyrap). Supervisor status was not updated in Zabbix. Note we were waiting for a new release.

=== Inform Apertif users ===
Use apertif_users@astron.nl for communication with users. Add RO admins too.

=== Supervisor on LCU's crashes ===
Supervisor starts too early, should wat for NFS. Fixed a few days later by Teun.

=== Update order ===
Reinoud: Wait with update of the ZFS replica servers before production is ready. Put proper order in procedure!

=== Jenkins slaves not tested ===
Arno: Our checklist went well. What was missing was: check if Jenkins slaves are up. (The home of Jenkins was moved)
Alta: Ingest not configured properly. Test for apertif-> alta was not present.

=== Stopday duration === 
Arno: We expect 1 whole day for the sysadmin and the next morning for completion of the tests.

=== Spacealk update ===

Jasmin: Spacewalk host Wop76 needs to be updated before its hypervisor
