We want to deprecate the implicit systemd-data partition, and know that this
will be an interface change.
We can maintain backwards-compatibility by supporting implicit systemd-data
partition for the single volume use case, and disallowing it for the
multiple volume use case. If you have multiple volumes, you need to be
explicit.
Note, you *may* reference the system-data partition multiple times across
different volumes, in which case we reuse the same filesystem multiple
times.
