assume i want to rebuild the same raid device on a completely different
system, cloning for example. "mdadm --detail /dev/md0" appears to be the
only command that will display all of the information needed to
completely rebuild a raid device with the exact same characteristics
(persistent superblock, chunk size, layout, etc.). has the format of
this file changed from back level versions? can i expect to see the same
format in the future?

also, is there any way with mdadm to create a raid device that does not
have persistent superblock? with raidtools there is a flag to indicate
whether you want a persistent superblock.
