Yeah, but a normal 'yum update' does that too, when you're just fetching
errata. It tends to leave two versions of various packages installed,
etc.

Yeah, some of those can be fun -- you're reminding me of things I'd
subconsciously blanked from memory :)

But they're not that common -- I think that if we _wanted_ a live
upgrade to work, it wouldn't be particularly hard to _make_ it work. And
to a large extent it _does_ work already. 

One of the reasons I'm happy using Fedora on servers is because I _am_
entirely confident that I can do a live upgrade on an unattended remote
system. I'm no more concerned about it than I am about any kernel update
on those machines.

Is it clever enough to switch back for F7? I already fixed the kernel :)
