He's talking about finding the root partition here. At that point you have the kernel and initrd loaded and no longer need bios. Assume you have /boot on a partition that bios understands and want to be able to arbitrarily move the drive that holds the / partition around. Won't labels, LVM identifiers and even md devices be found and assembled correctly from anywhere at this stage? -- Les Mikesell lesmikesell at gmail.com
