I'm not sure I'd agree with putting Docker volumes out of scope even in
a first pass.  Or for that matter, Kubernetes PVs/PVCs.

I understand the motivation for an initial take that's simpler, but doing
both seems really necessary for any nontrivial usage, and I worry
about putting in a lot of effort into a design that would have to fundamentally

At least though in modern d-s-s @rhvgoyal changed things to use an
auto-growing pool, which means there's a lot less up-front commitment,
and the task for an admin can be more "add PVs", not "manage LVM
and guess how much I need for images vs volumes".

Storage is a real challenge for a few reasons - IME it's where
kind of leaves one hanging.  Not that it's the fault of that project - it
just becomes highly environment specific (if you're in a top-tier
virt cloud provider like AWS it's easy to delegate to EBS volumes), but outside of that
things get less streamlined.

Note we're working on a new SPC design, it might be possible for
storaged to run under that.  But that's an implementation detail, the
design is more important.
