AIUI, what is needed is for fstab to not specify any partitions by
/dev/hd*, as that will change to /dev/s?*, with probably a different
number. I've been told that LVM volume entries won't need any change. The
Release Notes weren't quite clear about it.
When I upgrade, I'll do it by:
make a full backup
copy my existing FC6 to the "other" partition
get that working
edit fstab so entries refer to /dev/hd*
use the DVD Installer to do an upgrade install via the hard-disk
This allows me to use FC6 if F7 has issues, provides an on-line backup for
simple issues such as restoring the kernels that Anaconda will delete, and
has a separate backup in case of disaster.
