Only if you like asking and answering the same question twenty times,
which we know you do, Kevin. The answer that was given the last 19 times
is still valid: because /usrmove, and because grub->grub2, and because
other things that cannot be handled via a yum upgrade. It doesn't really
work to tell people 'you can yum upgrade with 13 and 14 and 15 but NOT
16 and 17 but NOT 18 and 19 and 20 and 21 but NOT 22'...
