Yes things get a bit more complex when using the new metadata format
and/or IMSM.

Usually I just do a mdadm -Ss before creating any arrays and use the
0.90 format and all is well.

We'll certainly need to add some things to the README_RAID.TXT and
probably make some changes in the initrd creation for the next release.
