Using that command gives this result:
jim at JimsBook:~$ ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 2009-04-09 04:31
188ba7f1-4de4-4961-9f4b-10dc11811e1b -> ../../sda3
lrwxrwxrwx 1 root root 10 2009-04-09 04:31 209049EE9049CACC -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-04-09 04:31 45DD-FC5B -> ../../sda1
lrwxrwxrwx 1 root root 10 2009-04-09 04:31
c8253db2-ac0b-4664-9e3c-837ce469a95d -> ../../sda4
jim at JimsBook:~$
which is the same as menu.lst. I did a check with gparted and it is
actually /sda4 as called out by the ls command. All of the UUIDs in
menu.lst are identical, so if the second kernel boots the first one
should as well. I'm thinking maybe kernel related? If so next update
might fix.
Thanks, I'll keep plugging on this.
Jim
