Somehow we manage to get by with testing only one Ubuntu version per OpenStack release.
I'm quite sure there is always an overlap, otherwise grenade would not work.
Good point, I hadn't considered grenade. While we don't expressly mention the platform used for upgrade tests as part of the PTI, you are correct that we deploy release N-1 on the default node type for release N-1, then upgrade it in-place to release N and run a battery of tests against it. Technically we do test the new release on the old platform (at least for projects which tests their changes or are otherwise exercised by grenade), even though the PTI says we can drop support for the Python version on that platform. If someone wants to work on running grenade on centos-8-stream nodes for yoga, we could ensure that's still a viable upgrade path the same way. -- Jeremy Stanley
