FWIW, I'm totally on board with the idea of not switching to systemd in
F15 --- and even if I wanted to do that, it's pure luck that the problem
doesn't apply to F14->F15 upgrades as well, where such an option is
certainly not available.  The reason F14 escapes the problem is that
we went to a new mysql major release series in F15, something that
happens maybe once every three years or so.  (The last-minute upgrade to
postgresql 9.1.x in F16 is likewise the only reason why I'm not bitching
about this with respect to postgresql too.  And I suspect a whole lot of
other packagers are up against similar issues, or will be if they take
back-branch maintenance seriously.)

What I want is a packaging guideline that doesn't simply blow off
the problem of upgrading packages in pre-systemd branches.  It's not
an acceptable restriction, and I'm astonished that anybody ever thought
it would be.
