why no new GNOME 3 snapshot in F14?

[Colin Walters]

I just had a discussion with Owen about the state of F14+gnome-shell,
and wanted to give an update on why we decided not to try updating it
from the current state (last updated Jul 13), and concentrate on F15
instead.

So most of the development has been happening in git/jhbuild, and we
haven't even managed to get rawhide updated due to the XULRunner
changes (work on rawhide is proceeding now,
https://bugzilla.gnome.org/show_bug.cgi?id=622896 for the curious).

Now, multiple things would need to occur for F14:
  - Separate clutter 1.4 parallel install package
    Impact on critical path: None.  Sort of ugly is the only thing.

  - Updated GTK3 package
    Impact on critical path: Low/None (some things in F14 oddly
require gtk3 that shouldn't, like seed...needs investigation).  But
we'd *also* have to look at either updating packages like
gnome-desktop3 (or removing them).

  - gobject-introspection 0.9.5+
    This implies simple rebuilds of a lot of packages for the
lookaside GIR/.typelib data, which is straightforward.  However,
updating to this version also implies pulling in a new pygobject,
which has had quite a bit of code changes.  Upstream feels confident,
but it's just one thing that weighs against an update (a possible
alternative path is to disable introspection from pygobject).

So the alternative here is:
  - Add a warning/note to F14 gnome-shell that it's old and to:
  - Make it easier and better to run F15/rawhide.  Which involves
fixing the problems there, and scripting the rpm/yum foo better to
make the switch, and being a lot more aggressive about preventing
regressions.
