And to add insult to injury... just had a lucid kernel upgrade (to -17)
on that machine and it didn't show up on the grub2 menu after restart.
So I had to go back to karmic and do a 'sudo update-grub' in order for
it to show up.
So, I'm thinking that Goh's method of putting grub it it's own partion
is probably the only sensible way to go (no pun intended).
Yo Goh... I vote that you & Tom H write a multiboot grub2 app (gui
preferred of course) or modify startupmanager to sort all of this out
:-) Or modify/add to the https://help.ubuntu.com/community/Grub2 page to
point out these issues/techniques?
