This would make the logical view from within softraid_raid1 appear the
same (e.g., an `sd3` regardless of which chunk it is being read from),
but the underlying `sd{0,1,2}a` chunks that would be backing it up
would still be different, because metadata
(http://bxr.su/o/sys/dev/softraidvar.h#sr_metadata).
