Hi, I've recently installed FC5 for the first time, so I'm sorry if this is a stupid question: In my Yum repo list I can see a lot of repos that are not being used by my Yum, such as "core-source", "extras-development", "legacy testing" etc etc. Am I right in assuming that some of these are beta-versions of new packages, and would it be a mistake to use them? I realize that some might be unstable, but couldn't I just uninstall the new versions and reinstall the old ones if something was too buggy? I guess I am asking: which repos should I use if I want to stay "bleeding edge", and which one should I avoid under all circumstances? thanks! Morten
