I agree with the idea, but it should be better phrased. It's not the way
the test is implemented that matters, but what's being tested. The fact
that the test is done by AutoQA is really neither here nor there.
It would be safer to explicitly define the types of tests we want all
updates to pass: set out exactly what the 'obvious' hurdles every
package pushed should get over are (i.e. dependencies should be sane).
*How* we choose to test that is really just an implementation detail.

This feels broadly correct to me at present, and that's what I'll say at
the meeting if input from non-FESCo members is okay. I think Matt's
proposal is far too much of a leap at present; it may be true that we
can drive much more feedback in Bodhi than we currently get, but we
should prove that *before* we push a policy that relies on it happening,
not after. I know there's a potential chicken/egg problem there, but we
haven't even really tried very hard yet.
It also has other issues that have already been discussed, that are
mainly shortcomings in the current Bodhi process. As many have pointed
out (and QA has basically accepted), relying on a simple overall Bodhi
'score' is pretty unreliable at present, because we have no really good
process for defining what positive and negative Bodhi votes actually
mean. It's just not a robust enough process to make all updates depend
on getting a hard-defined overall Bodhi score at present. It can go
wrong in both directions; updates that shouldn't get pushed can get +3
(the obvious example being a kernel that boots fine for 7 people and
breaks for 3 would score +4), and updates that should get pushed might
not get +3.
Right now we should limit reliance on Bodhi to only critpath packages at
most, and even for that we do need to tighten up Bodhi procedures quite
urgently. And it shouldn't rely on an arbitrary combined
