# This variable can (and probably should) be overriden by their common_X files
# that are sourced. The reason is because future EL's can potentially change up
# which repos are module based (whether adding/removing). This is something to
# keep in mind. For example, Fedora (sanely) has a "base" repo and then an
# updates repo for both their regular packages *and* their modularity repos.
# This obviously makes sense and I can only hope Red Hat decides to bring that
# back in some way.
