Public bug reported:
Whenever I run update-grub, the entries in grub.cfg for one of the
partitions has conflicting UUID entries, like this:
---------------------------
menuentry "Ubuntu, with Linux 3.0.0-21-generic (on /dev/sda8)" --class
gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos8)'
search --no-floppy --fs-uuid --set=root
78e9d241-98f5-409e-87fa-f69f5d5f0250
linux /boot/vmlinuz-3.0.0-21-generic
root=UUID=fccd57a0-f381-4d59-81b9-d66c8b082d3c ro quiet splash vt.handoff=7
initrd /boot/initrd.img-3.0.0-21-generic
}
---------------------------
This prevents that partition booting. If I manually edit the grub.cfg
to make the 'root=UUID=' entry match the '--set=root' entry, then that
partition will boot OK.
I have a number of partitions on this PC thus:

This is the output from 'sudo update-grub':

This problem also occurred in Xubuntu 11.10 and now is occurring in Xubuntu
12.04.
