Have you considered man yum? downgrade Will try and downgrade a package from the version currently installed to the previously highest version (or the specified version). The depsolver will not necessarily work, but if you specify all the packages it should work (and thus. all the simple cases will work). Also this does not work for "installonly" packages, like Kernels. downgrade operates on groups, files, provides and filelists just like the "install" command. mark "and no, this isn't twitter, and no, know is not spelled no"
