^^-- This workaround does work; it may limit those run multiple raid arrays 
with different types superblocks in each array that need to be loaded via 
do_mounts_md.c -- but if you are using all superblock v1.0; this does get 
the job done.

Many thanks for the time you spent debugging this with me today.
