Oh I forgot to mention you have to edit /etc/grub.d/*
and /etc/default/grub now, but that's also noted in the top of grub.cfg
dpkg/ucf take care to preserve your changes.
You can also rename the files in /etc/grub.d if you don't like the
order, but I'm not sure if dpkg would then tell anything at all if we
change the files in the package or if it silently accepts it that you
don't want to have that file (from it's perspective, it can't know that
you renamed it.) and so you would never got an updated version.
