Generally I agree that too much magic should be avoided.
But I see one use case where it might be useful: Expanding or
shrinking a HAMMER filesystem. Right now, all volumes
have to be specified. If, after an expansion, you miss to add
the new volume, you can easily render the box unbootable.

What I imagine would still need to mount a filesystem explicitly,
just that the volumes are determined automagically.
