The problem is though you'll be left with a half-upgrade, some
packages will have been upgraded, some will still be the old. If
you're lucky, it needs no more than apt-get dist-upgrade, if you're
unlucky it can take major futzing.
I dont see how an anaconda based upgrade could avoid this problem

The debian people and Connectiva people have been thinking just as
long about apt ;).
That said, I guess RedHat have more scope for adding package specific
hacks to anaconda.

I test apt-get dist-upgrades on a throwaway test box first to see how
it works out. Will let you know how FC2->FC3 goes when I get around
