Bug#481542: grub2: please user triggers for menu.lst update

[Jon Dowland]

Package: grub2
Severity: wishlist

please consider using dpkg triggers to update the menu.lst
file, rather than do it for each kernel image install or
remove.

a disclaimer. I'm not using grub2 on this
machine at present. I was going to file the following
against grub 1 when I saw the disclaimer. I checked the
changelog and bts for mention of triggers, and checked the
source for a triggers file (which I couldn't find). From
when I did use grub2 (I had to back out at the time) I
believe this is relevant to grub2. There is a chance I am
wrong in which case I apologise.

However, if I'm not, hopefully this will then avoid
situations like the following:
