With my method, the target on the system is a md raid 1 device. You
need to configure grub to point to the 2 devices as if they were
independent, to deal with one of them failing.
Here's the message I gleaned this from when I set it up a while back:
http://www.linuxsa.org.au/pipermail/linuxsa/2003-July/058253.html
The /boot partition will still be mounted as raid, but the MBR's must
be installed on each device or it will not boot with a failed disk.
So, when you do software updates, you dont need to update each side of
the mirror separately, it will write to both.
