Aha, this now makes a lot of sense. Do we have any pactests to ensure
multiple depends on the same package will work? I think we should make
some if we don't have them (one that is satisfied, one that is not).
Something testing what would happen if you wanted to upgrade the
kernel but could not upgrade because module deps were not satisfied
would be cool.
