We should just use release epochs, people might hate them for whatever

The problem with this system, which has been pointed out before, is that
upgrades using the Fedora N release DVD on an up-to-date Fedora N-1 system
will replace newer versions of packages with older ones -- this is bad.

"Bad" .. a yum update after the upgrade will fix it.

What if the new version is incompatible? New versions are normally upwards compatible but not backware compatible.

Say you install a new mysql, then upgrade the tables, newer mysql will read those tables, but not older mysql.
