Fedora has one:
..and then run dist-upgrade. Beware, you're stepping to largely untested
grounds
here, I don't recall seeing success/failure reports of the process. Chances
are
it works just fine but you never know until you try - trying it out on a
crash-test-dummy box first is heavily recommended.
I upgraded my (non critical) work station (p3/1ghz, 512mb, i815 board) yesterday
using apt-get. Had no problems getting it back up (even with a 2.6 kernel), but
the X/Gnome fonts seem a bit "off" to me. (read about this in an earlier thread
on this mailing list). Have to play with it a bit more to see what's broken ;)
