Subject: Re: Why do I get different results for 'mdadm --detail' & 'mdadm --examine' for the same array?

repeating the process on another box, i just noticed that these two
results' UUIDs match exactly,
/dev/.mdadm/map /dev/md/0_0 52f5b43c:e83f7e2a:be6ad32e:0536ab0e
mdadm --detail --scan /dev/md/0_0 52f5b43c:e83f7e2a:be6ad32e:0536ab0e
but the OTHER array's two UUIDs
/dev/.mdadm/map /dev/md127 79fb7ad4:289bfae5:86c535ff:202960f2
mdadm --detail --scan /dev/md127 d47afb79:e5fa9b28:ff35c586:f2602920
are 'transforms' of one another; e.g.,
mdadm --detail --scan /dev/md127 d47afb79:e5fa9b28:ff35c586:f2602920

79: 28: ...
/dev/.mdadm/map /dev/md127 79fb7ad4:289bfae5:86c535ff:202960f2
what's happening here? that can't be a coincidence.
is this a bug? or maybe an artifact of the type of array?
