Besides, the Linux RAID arrays usually do no reside on whole raw disks
but on RAID partitions. GRUB's boot image and core image are usually
installed on each disk outside these partitions. This way all the
sectors needed to load GRUB's core image can be found on each single
disk, regardless of the RAID level.
