I believe the problem is related to Redhat's use of partition labels
by default on 7.x and 8.x. Makes it easy if the drives master/slave
changes but causes problems for other things like this.
For example, my /etc/fstab looks like:
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext2 defaults 1 2
LABEL=/home /home ext3 defaults 1 2
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
Attempting to boot a system with two drives (or multiple partitions on
the same drive) configured like this will confuse the system. So the
first step would be to change the LABEL= lines to /dev/<device> (i.e.
/dev/hda1 /boot ......etc.)
Next issue is how you want to boot the two systems. One boot partition
or two? With one boot, make a copy of what is already there, then
install the new system, allowing it to overwrite the old. Then merge
the two boot partitions by hand. They will already be a different
kernels, etc. so it shouldn't be too hard.
Then I would recommend booting the second system or mounting its drives
in the first temporarily and making similar changes to its fstab that we
did to the first.
Then reboot and I believe it should work....
Good luck,
