Sorry for the delay in picking this back up. I do have a _slight_ concern that someone with a crazily small /boot will end up being broken by the new backup code, but agree that it is better than the current situation. As grub produces udebs, this will need a KiBi-ack, so tagging and CCing accordingly. Regards, Adam
