While it might *happen* to work by luck, the backdoor interface it
uses would definitely *not* be correct, as it would still see the
wrong cn_nameiop.  To make a file system like this work correctly, you
would still need another interface to get additional components.

I'm definitely not interested in making portal even *more* klugy.
