+1 for the number of disks plugged. UUIDs aren't of any use when installing grub to the MBR because they're a property of the filesystem and not the disk. You might be able to use "/dev/disk/by-id/..." instead of "/dev/sdX", at least in more recent grub versions. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
