I've asked some of these groups to do that, but it's like asking any
other upstream.  A lot of the problem stems from things like anaconda
using more and more of other bits in the distro, which change
significantly right at the freeze date, breaking anaconda.  So while
we're waiting for anaconda, it's really because something else changed
late.  I tried to mitigate this by setting the feature freeze back a
week from the beta freeze, so that the nasty changes land a week before
we freeze for beta, giving folks like anaconda time to survive.  It
almost worked, and maybe we need to extend that back even farther.

That's a fair point.  We don't well document or communicate the "points
of no return" as it were.  We've also had to discuss how we set those.
In the past it was the last point at which we could compose and upload
the bits to the master mirror in order to have enough mirrors synced at
release day.  Now it seems more that we have to make that decision
within enough time to spin up (or down) the marketing machine, which
looks to require more leadtime than the mirrors do.

That's a bit hard to determine easily and programaticaly.  I've all but
given up on my quest to reduce the number of updates.  It's just doesn't
seem to be in line with the desires of the package maintainers, whether
or not it's in line with the desires of (some of) the project leaders.

If there was a way to do it without adding stress and work needed to
teams like releng, installer, etc.. that would be possible, also if they
were done without freezes.  But the overwhelming requests I get are
of /less/ of these test releases rather than more.  If our release cycle
were 9 months or even 12~24 months it would make a lot more sense to
have more milestones.  But with only a 6 month cycle it gets hard to
find time to do development in between all the already existing
milestones.

That's what we hoped to have with the post-beta snapshots.  Hard to say
if it's had any real impact, likely due to the short amount of time
between beta and the final freeze/preview release.  If we attempted to
do snapshots leading up to the beta that might make it more noticeable,
but then we're back in the realm of more milestones instead of less.

The rawhide trees for at least the past month are kept in the Fedora
infrastructure and are even available by a public url.  We haven't
tagged any of them as "stable" though.

If we didn't care to let the mirrors sync up we could "release" it
earlier.  However what good does that do when nobody can /get/ to the
release because none of the mirrors have it, and the ones that do can't
help sync to those that don't because users are tying up all the
bandwidth?

Less snapshots for them to worry about, taking time away from the
development and bugfixing effort.  Automated testing.  Better bug
management.

What looks more unprofessional?  Delaying the release, or hitting our
date and releasing with bugs that eat people's data?  Or releasing with
broken graphics for large swaths of users?

The marketing machine has very strongly requested that we only do
releases on Tuesdays.

At first the plan was just Alpha, Beta, and release.  But people really
wanted a final snapshot after the final freeze to base their tests on,
so Preview came to be.  Now we're talking about dropping Alpha because
of it's dubious value at that point in the release cycle, which would
reduce us back down to 2 major snapshots during the cycle, Beta and
Preview.  That's what the F12 schedule has right now.

You'll have to enumerate why that is.  One reason I've avoided this is
added confusion as to when the "release" happens.  If we created that
directory and put content in there, would we have then released Fedora
12?  When does it become "released" and thus trusted?
