It worked in a way, but was an interesting case.
As I see it, the general series of events went something like this:
-10 was *generally* ok
-11 fixed a few bugs, but introduced the nasty "breaks grokking of
/etc/groups", down karma'd
-12 fixed some other bug, down-karma'd for not fixing -11
-12.999 got massive up-karma for fixing -11 problem, *but* introduced a new
problem/regression. Got pushed stable.
-13 was, of course, damage control from the fall-out from 12.999...
Now, I'd argue the process worked up to -12.999, regressions were kept out
of stable updates.
The fail(*), imo, was with 12.999 going stable containing known-regressions.
So, any suggestions, if any, to prevent any similar series of events?
