I was in a hurry - this is the wrong way to do this, but it works, and it should be relatively simple to implement this the correct way. I just copied /etc/grub.d/10_linux to /etc/grub.d/11_linux, modified 11_linux and ran upgrade-grub(2). Seems to work OK, but it's a nasty hack. My preference would be to create new custom variables in:- /usr/sbin/grub-mkconfig and then call and populate them in:- /etc/default/grub after modifying 10_linux to use them (sic). NOTE 1: use chmod -x to stop files in /etc/grub.d from being acted on by update-grub *regardless* or name or extension. NOTE 2: I *like* grub2! /etc/default/grub is simple by design, you can make it as complex as you like. /etc/default/grub====================================================== # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg.
