Oh really, I hadn't considered that difference - thanks! We'll get to
work on testing that. Upgrade to Victoria went flawlessly yesterday
(except for one small mistake) for control plane and compute. Now we get

Now we've made the investment to get properly moved into Kolla
Ansible[1], our upgrade sequence is far smoother than before.

Greg.
