if i were to read the superblock myself, would it look different for
devices created with mdadm than with devices created with raidtools? i
am trying to figure out a way of knowing which tool was used to create
them in the event that we need to rebuild them. any difference i can
count on consistently is what i am looking for. the problem is that if
we recreate raid devices using mdadm and their init scripts dont start
the raid devices then the devices will not be assembled, and could
possibly cause the system to not boot.
