I concur. I'd like to be able to specify the whole path somehow. I'm
looking for the standard way to do that. I also need a way to just say
"Find a ZFS pool so we do what we do now" and "Find ZFS pool FRED and do
what we do now"

Someone (maybe you) on IRC suggested zfs:/pool/file/system:/path/to/file
since that's what's used now. It doesn't look like a typical URI, but
looking at RFC 3986 I see that it fits the ABNF at the end, as well as
being congruent with some of the examples. Since there's no 'authority'
section, it's fine. I'm not aware of needing any authority or credentials
to access the pool, so I think that's fine.
