Hi, what is the best procedure to revert (downgrade) all packages of a specific repo, e.g. if distri comes with KDE 3.4.0, and KDE 3.5.1 is available from an auxiliary repo. Upgrading is as easy as enabling this repo and running "yum update", you all know. Now considering, that there are some unacceptable bugs, I wanted to revert to the base packages. Manually running "rpm --oldpackage" with all previously updated packages and their dependencies is a tedious task (given, they're scattered over several repos..). Anything yum can offer to ease that unfortunate exercise? Pete
