I don't think it particularly makes sense to expose the config drive
via NVDIMM - it wouldn't solve any of the problems that config drive
has today and it'd be less portable wrt guest OS.

Rather I was suggesting we should consider NVDIMM as a transport for
the role device tagging metadata standalone, as that could provide us
a way to live-update the metadata on the fly, which is impractical /
impossible when the metadata is hidden inside the config drive.

But before doing that though, I think it'd be worth understanding whether
metadata-over-vsock support would be acceptable to people who refuse
to deploy metadata-over-TCPIP today.

Daniel
