I am not surprised that you disagree...

I mean "grub-rescue>"; this is the CLI prompt that comes up when you
boot and grub cannot find a usable grub.cfg. You then have a limited
set of grub cli commands to identify /boot/grub and load the "regular"
grub CLI (and subsequently boot). With grub1, you would have to boot
from a live CD or the network in order to fix such a problem.

Everyone (or almost) was misusing menu.lst in the past.

What you were supposed to do (on Debian/Ubuntu) for grub1 was edit
menu.lst's options in menu.lst in between "Start Default Options" and
"End Default Options" and then run update-grub.

What you are supposed to do for grub2 is edit its options in
/etc/default/grub and run update-grub.
