The bootloader or mkinitrd typically tells the kernel what the root disk
is, so that's not a big deal. The boot disk, OTOH, is tough. Right
now, we just assume the sysadmin knows what's he's doing, when he
installs lilo or grub on a disk. You care about the boot disk when
installing lilo... maybe there are similar situations too which I do not
recall. As Alan said, besides EDD (only on newer boxes) there's really
nothing.
