Forgot to mention that this is not quite enough to make update
metadata work, since I still get exceptions from within the bowels of
yum which indicate that the repos in the loop are not sufficiently
setup to work; adding a repo.dirSetup() to the loop seems to fix this,
and I acutally got a (nonworking) "More Information" button now for my
security update...
