Also it is not a good idea to reuse the /home partition in an upgrade of fedora ( or new install )
the versions of software used in the new version might NOT be compatible with the old versions
the new version of fedora might NOT even be using the same programs as the old version
I find this an interesting comment. I've never had any trouble with maintaining a /home partition over new installations of fedora. To avoid the incompatibility mentioned above, before I install, I delete all the relevant configuration files in /home, which means removing all of the relevant dotfiles. The new installation recreates them all in the new versions. With programs that don't actually change much like my window manager, I keep my configurations ... same with my Xdefaults. But for browsers and desktop stuff and other programs, it all gets nicely recreated. The great advantage of maintaining a /home partition is that you don't have to copy your data off and back with each installation ... just copy off for backups.
