I have never done clean reinstalls instead of updates. Sure, one or two things may break, but it is a lot easier and faster to fix something than it is recreate everything. My desktop was first installed with fedora 3 and has been upgraded since. I always did straight yum upgrades, but now I like the preupgrade system.

Here are the details: http://www-uxsup.csx.cam.ac.uk/~jw35/docs/rpm_config.html I like to run 'updatedb' and deal with 'locate rpmnew' and 'locate rpmsave' after the upgrade. > - What happens to deprecated or obsoleted packages?

'yum list extras' will help deal with the old junk. > - Have people had stability issues with doing a distribution upgrade > or does it usually "just work" out of the box? My desktop just upgraded fc9->fc10 without a blip. My laptop required a small xorg.conf modification after the same upgrade. No biggie. > - How long does it take you to be up and running with an upgrade? > (start-to-finish) 'yum install preupgrade' - 30 seconds. Run 'preupgrade', select Fedora 10, walk away - 30 seconds. Click "Reboot", walk away - 1 seconds. Once booted, deal with rpmsave/rpmnew, and extra packages - 30 minutes. > - Do you see any problems in skipping F9 and going directly F8->F10?
