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.
