Hmm, but *bin/* dependencies are already in primary, right? (At
least for the xml version.) So that doesn't hurt.

AFAIK you also have lots of dependencies for stuff in /usr/lib,
thats why you need to transfer the complete filelist.

Would it make sense to find out which directories are used in
the dependencies and also add them to the primary data like
the *bin/* files?
The idea is that you have to download that part of the filelist
anyways if you want to do depsolving (i.e. for yum install/update).

You would need to store the used glob patterns somewhere in the
primary file, so that yum knows when the primary data is sufficient
and when it has to download the complete file list.

Cheers,
  Michael.
