In lilo.conf: root="UUID=77ae4251-631f-4656-a365-c5723f5c5da8"
image=/boot/2.6.28-4 label=2.6.28-4 read-only root="UUID=77ae4251-631f-4656-a365-c5723f5c5da8"
The /etc/fstab entry works, but not the LILO one.
Also I found a bug (OOPS) with a box I was testing the new subsystem (SATA vs. old IDE) with, will send a bug report shortly.
Justin.
