Whatever you do, NEVER use the UUIDs of partitions, use the UUID of the
md devices.  The worst failure scenario involving MD and idiotic tools
is for a tool to cause a component device to be mounted instead of the
MD array.

This is one of the reasons why the new MD formats that offset the data
inside the component devices exists.
