At least as far as I understood this proposal, the idea was to create a
separate filesystem for this that would be mounted on /dev.  The filesystem
would then get the device name to resolve to a driver and would pass the
name to the driver open routine, so the driver could in turn resolve things
like driver number or partition.

It's totally independent of whether the root filesystem is mounted via NFS,
FFS or anything else.
