Comment 2 for bug 377613

I understand what you're saying (can't honestly say I understand UUIDs or what they're for though...)

In my case, regenerating menu.lst wouldn't have made any difference, because having a failed installation meant that I had to restore it from my dumps, where the installer couldn't (and shouldn't) have touched it.

So really the problem is the use of UUIDs in menu.lst. If that had been pointing at /dev/sda1 or hd(0,0) then restoring after a failed installation wouldn't be a problem.
