[Pulp-list] Using Pulp to "merge" multiple RPM repos into one?

I think your plan is spot-on. In usually makes sense to have a 1-1 mapping
of remote repos to pulp repos, and to keep the pulp repo as a simple mirror
of that remote repo. From there, you can copy out of the pulp-hosted
mirrors to compose new repos with whatever mix of content you like.
