An interesting take on zfs (and anything else we didn't set up from
the get-go) is that we envisioned developers might
want to craft plugins for ceph-volume and expand its capabilities,
without placing the burden of coming up
with new device technology to support.

The other nice aspect of this is that a plugin would get to re-use all
the tooling in place in ceph-volume. The plugin architecture
exists but it isn't fully developed/documented yet.
