I use it to build FC9 and FC10 packages via Mock. Unfortunately, it looks like it doesn't want to use the old RPM database from the previous FC8 install. How do I clobber all of this to that the database gets written afresh? Apparently, "mock -r fedora-10-x86_64 --clean" isn't adequate. Perhaps "mock --nuke" would be useful here following an version update to zap stale state? Or should I just uninstall and reinstall mock?
