...which is the easiest way to deal with this actually -
1)boot using your install discs with "linux rescue" [your RH8 system will be
    mounted under /mnt/sysimage if you need it. You won't.]

2) find which partition is labelled '/' using
#  e2label /dev/hda2 (for example)
just change the number until you find the right partition. Personally I
would
write them all down to keep a record in case you have problems in the future

3) relabel the offending partition
#  e2label /dev/hda2 /oldroot (or whatever you wish)

then when you slap it into your new machine there will be no conflict, and
you
can mount it manually anywhere you like.
or add a new line to your /etc/fstab
LABEL=/oldroot	/mnt/oldroot	ext3		0   0
You may need to do the same with the /boot partitions, to ensure it uses the
correct one.
However this is about 5 minutes work in total.
changing it back is simplicity itself.
Alternatively do away with the label assignments entirely (which (IMHO) are
a
royal PITA) by editing your /etc/fstab to use the device nodes instead.
