Specify grub root with uuid?

[Philippe23]

Grub disagrees with my kernel over drive ordering. I'd like to move both to UUIDs or Labels. I know how to do so with the kernel parameter, but I do not know how to do so with the grub root command:

title=Gentoo Linux (3.8.3) Custom Kernel (new-drive)
root (hd1,3)
kernel /boot/kernel-3.8.3-hardened root=/dev/sdb4

Anyone know how?

IIRC grub 0.97 can do this with an initrd for normal partitions.

title=Gentoo Linux (3.8.3) Custom Kernel (new-drive)
kernel /boot/kernel-3.8.3-hardened realroot=SOME-RIDICULOUS-STRING-01234
initrd /boot/initramfs-3.8.3-hardened


And without for GPT partitions.

title=Gentoo Linux (3.8.3) Custom Kernel (new-drive)
kernel /boot/kernel-3.8.3-hardened root=PARTUUID=SOME-RIDICULOUS-STRING-01234

Yeah, that's the kernel options, an argument to the kernel that's resolved by the kernel. The part I don't know is how to change the bold+italic line in my post, the one that tells GRUB where to find kernel itself. "(hd1,3)" is the part I'd like to replace.

If /boot/grub and /boot/ live on same partition, you don't need the bold+italic line.

use labels fo filesystems

Legacy Grub can't handle UUID for it self, you would need to upgrade to grub2.
