The auto-generated name right now would be:

"<unique-nic-name>::nvram"

You are right that that is also a path.  And I now think you are right that we 
could just s|::|/|g and declare that names are paths.

The only problem with this is it introduces a canonical path format.  That may 
or may not be a bad thing..
