Hi,
AFAIK, The update-grub script is used to generate a new menu.lst rather than
"updating" the menu.lst as the name suggests. LILO required updating it
everytime a change was made, but that is not the case with GRUB. All changes
to menu.lst are automatically accepted (without the need of running any
script such as update-grub).
