This would also meen the upcomming RHEL5 (derived from FC5) will be incompatible
with RHEL4 (derived from FC3) and RHLE3 (derived from RH9).

The user friendly version would be not to change an existing partition during boot
time without a warning.

As current solution I can only backup my boot and home partitions, format them
under centos4, restore the data and forget FC5.
