The biggest "problem" here is with the default setup of using the mirror
list, mirrors are often not in sync enough that you download metadata
often.  One of the lower priority things for pup is making it easier to
select the "best" mirror for a user instead of always using the mirror
lists.

For mock users, you almost certainly want to do this, though and I'm not
sure how to really make it easier/more obvious
