I have a Fedora 21 system, but I would like to update it using repos from Fedora Core 4.
I have found this article - How to Use YUM in Fedora Core 4
- that allows changes to be made to the yum settings, so that you can run yum on Fedora 4.
Is it possible to setup Fedora 21 to point at this repository over the normal one?
I realise that this is not good practice, but I would like to test out a theory to see if this will work.
