Due to the ordering dependency that Linux assigns to drives this is not a deterministic assignment we need to use explicit device mappings in MAAS.
We ran into this with a customer that had allocated RAID devices in different orders which assigned /dev/sda and /dev/sdb randomly. This resulted in an encrypted ephemeral space on the root drive and not the dedicated drive that was intended.
Perhaps the check would be "NOT regex /dev/sdX etc..."
