Then don't use 3rd party repositories... A repository is not "just" a collection of packages that can be installed on Foo, it is a system of packages built and tested for use together on Foo.

Using one set of (coordinated) repositories prevents that today (and that is exactly the problem you are trying to solve...) -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
