It is, however, possible that "mdadm --examine --scan" could grow an option whereby the device names are given as /dev/md/UUID:OF:THE:ARRAY:THAT:WAS:FOUND This, toogether with giving 'auto=mdp' could avoid and issues with minor number conflicts. Then: echo DEV partitions > /etc/mdadm.conf mdadm -Es --new-flag >> /etc/mdadm.conf mdadm -As --auto-mdp would assemble all arrays, which is what you claim to want.
