How much is likely to break if you keep a locally installed /boot
partition with it's anaconda-crafted module set in the initrd, but
wipe and completely replace / and any other partitions with a copy
from a machine that has somewhat different hardware? Assume both
machines are running the same kernel versions and the change is done
while running from the rescue CD or other livecd boot.
If you have similar boot controller, it could work. But if boot
controller changes, and needs a different driver, it won't boot. You
will get a panic when it can't find the root.
No, that's the whole point of keeping the local anaconda-generated
initrd that will be in /boot. You'll have the right driver there when
you need it. The messy part is that after you mount the new /, you'll
be reading the rest of the config from a /etc generated elsewhere, but
if /etc/fstab matches, the rest can probably be fixed. My question is
what else is likely to be broken or show up later as a problem? I
suppose if prior kernels still installed don't match you wouldn't be
able to 'rpm -e' to clean them up.
