Public bug reported:
My gutsy system (i386) has been continuously updated since Tribe 2. I
update exclusively with apt-get update, upgrad, dist-upgrade.
The last two kernel upgrades have fudged my grub menu.lst. The kernel
and restricted modules and initramfs update successfully, and the grub
update lines in the upgrade "look" normal, but under the covers it's
wrong for the ubuntu stanzas. Other systems (this is a multi-boot
system) are not affected.
Here's an excerpt from the corrected menu.lst
. . .
## ## End Default Options ##

### END DEBIAN AUTOMAGIC KERNELS LIST
After a kernel update, the new kernel stanzas are added, and all the
ubuntu kernel entries have
root (hd0,7) and the UUID is no longer that of hdb3. I failed to record
the actual incorrect UUID.
ls /dev/disk/by-uuid -al and blkid show nothing for hda8, an empty
partition. This partition used to contain an earlier ubuntu system,
removed before this problem reared its head.
1. How can I fix this?
2. How can this be cured permanently?
It's a super PITA to need to boot an alternate system and repair the
menu.lst manually.
