How to prevent changing UUIDs on install?

You're welcome. I assumed  when I answered that you were momentarily
confusing update-grub with grub-setup or grub-install...

Your pastebin upload looks like grub-mkconfig, which makes sense
because if you look at the official grub2 wiki, as of 2008 (when that
page was last updated; I don't know the exact date), there was no
grub-mkconfig and update-grub was listed in the man page as the
executable to create grub.cfg.

Further confirmation: grub-pc in Hardy is at 1.96+20080203-1ubuntu2
and it does not include grub-mkconfig. See:
