Right.  If you want to have things this way from the start, we'll need
to make it easy to opt-out of this new default, and reconfigure docker
for other storage.  Doing it in a cloud-init script would work, though I
think the long term best thing would be to have a tool for this,
"docker-lvm-admin"?

There's also the aspect that what I think a lot of people will *really*
want is to have Docker volumes be on persistent storage, and Docker
images/containers on ephemeral.  After all, you can just "docker pull"
the binaries again.  This isn't supported AFAIK by docker yet, but we'll
get there.
