Oh Oh. I forgot. My / is ext4. F12 can't boot off ext4 filesystem. But
I know F14 *can*. Hmm.

So if I go ahead with this plan to get rid of my /boot partition, I
won't be able to boot back into F12 to run preupgrade.  AAHH! This is

What will happen if I just copy /boot to /boot2 in / partition.
Then change



rename /boot to /boot1  (original boot dir)
rename /boot2 to /boot  (new boot dir)

fix  the new grub.conf to point to the second raid array (not the first)

So my original /boot array is still there but renamed to boot1.
Then I run preupgrade. Will that work?
