Hi Randy,

Any further thoughts on this? This seems like it would be a pretty
desirable feature for many users. Also, am I correct in stating that this
functionality did exist in the 1.x version of Pulp, allowing you to
whitelist or blacklist content, and therefore restrict what is synchronized
to an internal repository? I believe this feature was outlined here:
