I wonder, if we have a gate which runs through devtest entirely, would
that reduce the instances where we've broken everybody? Seems like it
would, but the gate isn't going to read the docs, it is going to run the
script, so maybe it will still break sometimes.
BTW I do think those patches should be first priority.

What if we just focus on breaking devtest less often? Seems like that is
achievable and then we don't diverge from CI.

+1. I think a note at the end of devtest_seed which basically says "If
you are not interested in testing HA baremetal, set these variables like
so and skip to devtest_overcloud. Great idea actually, as thats what I
do often when I know I'll be tearing down my setup later.

Agreed totally. The processes are similar enough that when the time
comes that a user needs to think about working on things which impact
the undercloud they can back up to seed and then do that.
