I run yum update nightly. I like to check [updates-testing] name=Fedora Core $releasever - $basearch - Unreleased Updates baseurl=http://download.fedora.us/fedora/fedora/$releasever/$basearch/yum/updates-testing manually from time to time. I don't want updates-testing automatically installed by the nightly run! What's the easiest way to arrange for this? I guess I could have 2 different configs. What I'd like even more, is to have 1 config that specifies the locations of all packages, but have yum automatic update only pick up some.
