None of the replies so far was quite correct. It exists more or less
entirely because of this old post of mine:


which wound up being quite a significant input into Bodhi 2.0's design.
Quite a few things in Bodhi 2 are there more or less "because that post
 suggested them".

The reason you're confused is we never really finished hooking up all
the ideas from that post. We put some of the necessary bits into Bodhi,
but didn't get any further than that.

So this separate feedback item exists, I think, basically because of
this idea:

"For me, one the principal benefits of such a system would be that we
could make the 'This update breaks critical path functionality'
checkbox an absolutely red flashing light, wailing siren emergency
button. I mean, you hit that thing and trucks roll from Fedora HQ,
metaphorically speaking. It would have a confirmation page which
clearly described the impact of asserting that an update broke
critpath, so we could be confident that it didn't get falsely triggered
very often. I'd suggest that:

1. Any update that is marked as 'critpath breaking' by a FAS-registered 
tester would be blocked from going any further in the update process
without manual intervention (no autopushes at all)

2. Any update marked as 'critpath breaking' by a proven tester would be
blocked from being pushed stable at all - automatically or manually -
until the PT modified the feedback or it was overridden by someone with
appropriately godlike powers (TBD, but probably not just the

3. Any update marked as 'critpath breaking' should probably get
announced on at least test-announce and/or devel-announce

4. Any update marked as 'critpath breaking' *after it has already been
pushed* would similarly trigger a major response: notify maintainer
very hard, notify lists, generally do stuff to make sure it gets
immediate attention"

But in the end...we put the separate feedback item into Bodhi 2's
design, then stopped. We never actually implemented all of (or any of)
the things I suggested there. So it's a bit of an odd duck at present.

Removing it is one choice, sure. Looking at those ideas again and
deciding if we want to actually go ahead and implement any of them is
another choice.
