So?  I've been planning for a long time to mirror my / and /boot
partitions, I've even got the empty disk to do it with, just haven't
done it yet.  And I've got my /home and /local partitions mirrored
which has saved my butt a couple of times now.

[ patch deleted ]

You do realize that this patch won't get accepted into the main
kernel, so you'll have to keep re-applying it (and remembering to)
each time you install a new kernel.  Is it really worth it?

For one thing, since mdadm doesn't care where disks are located, just
use a mdadm.conf file with a line saying 'DEVICE partitions' so that
it will search all partitions it finds for MD devices.

Then you have your filesystems listed by UUID, so they don't have to
be completely specified either.

Basically, let the computer find your data, and don't sweat where it's
located if you can help it.
