Hi Tom,

First, kudos for the new merge scripts.

I agree with Hans. This is why dot releases cannot have any new
feature in it, no matter how small.

Yup.

Finding the available hardware that is upstream, outside firewalls and
ready for deployment as buildbots, either all year round or on/off
during releases, is going to be hard.

If/when we move to Jenkins, this could be easier, but right now, it's
pretty hard.

Again, agreed. The decision process should be a conscious one, and
with review from the release manager, code owner, etc.

Simple scripting won't go all the way to providing that auditing path
and could make release branches unstable.

Release testing isn't complicated enough to automate that part, at
least not yet.

If/when we have more tests beyond the test-suite, we'll have to
investigate each individual test on their own.

For now, involving distros and large projects directly is the easiest
way to test the release.

cheers,
