Looking at the logic in the actual 'init' script in: /usr/share/initramfs-tools/
I see a case for a root specifying a UUID UUID=*) ROOT="/dev/disk/by-uuid/${ROOT#UUID=}" ;; This logic also caused my upgrade from Dapper to Edgy to fail because of my root on LVM. I had to change these back to /dev/mapper* addresses to achieve a boot. My LVM's also don't show up in /dev/disk/by-uuid -David -- No need to convert LVM volumes to UUIDs https://launchpad.net/bugs/54002 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
