I'm not 100% sure about this, but I'd say that the transaction handling
in the RPM database should be able to survive a crash in the middle of
an upgrade.  Either a package is installed, not installed or partially
installed.  If the post-install scripts are sane, it should always be
safe to completely re-install an already-installed or partially-installed
package.  So restarting the upgrade should be OK.

If the smart guys in Red Hat didn't think about this a long time ago,
I'll be very disappointed with them.

Don't go around recommending yum/apt as a way to upgrade to FC3.
FC3's installer does some magic to switch from a static /dev to
a udev-based one.  There are manual steps to do this if you're not
using anaconda (described in the release notes), but I don't think
mortals want to try that.

I haven't done an anaconda-based upgrade for a long time, but I'm
going to do one for FC3.
