This hasn't been my experience with grub2 at all. Just in case, I've just tested in a VM with two disks one with sid and one with quantal. sid's grub2 recognized and added quantal when (1) quantal's grub2 was installed and "/boot/grub/grub.cfg" existed (it used the kernel options in grub.cfg), (2) quantal's grub2 was installed and quantal's "/boot/grub/grub.cfg" was deleted, (3) quantal's grub* was uninstalled, (4) quantal's grub* was uninstalled and the first 446 of quantal's MBR and quantal's bios_boot partition were blanked out with dd. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
