  Hrm, apperently, this is all gone in 2.6, sorry for pointing the
wrong way.  The entire md.c was split up into it's own directory.  I
wonder if there is a way to permanently attach a given drive to a RAID
array, so it remains there if it's present or not.  You're right, I'm
suprised there isn't more on this online.  It's a GREAT idea to mirror
a local drive over an external mass storage drive.
