This is a different userspace on top of the device-mapper driver. The 
metadata reading code is in userspace, and part of it has been copied from 
LVM2. Besides LVM2 metadata, evms supports plain old partitions and provides 
bad block relocation.

I think that it cannot be supported. I will test now to see whether Debian 
can be installed on such /dev/md/meaningful_name array.

Yes, this is only for the passphrase.
