I think yum would be the logical place to handle this, because as the
problem is described, you could potentially hit it another way.

Do a clean install of Fedora 10. Then enable the Updates repository but
not the Everything repository. Try to update. I would expect it will
fail, because libudev0 won't be available for the NetworkManager update.

It seems that, the way we handle updates in Fedora, the updates
repository more or less 'depends' on the Everything repository. This
should therefore be enforced in yum somehow, in a way that anaconda will
respect. That should solve the problem in future in all cases.

(In MDV, FWIW, when this situation occurs - an update introduces a
dependency that didn't exist before - the package for the new dependency
is added to the updates repository, even if it has not been updated).
