Suppose you have md0 on sda1 and sdb1, and BIOS orders them in such way:
HD0: sda
HD1: sdb
And that you already have grub set up on sda (during installation or
however).
Then you do:
# grub

When you unplug sda, then sdb becomes HD0 and everything works as it
should (since root is on md, you don't need to change fstab). You only
need to make sure not to make initrd when the array is degraded, as this
won't boot when using SCSI naming scheme disks (including SATA), at
least that is what happens with sarge initrd-tools.
