The above snippet works.  However, 'guix substitute-binary' throws the
following error:

  guix substitute-binary: error: invalid nar end-of-file marker

Here's my nar rendering code:

  (define (render-nar store-item)
    "Render archive of the store path corresponding to STORE-ITEM."
    (let ((store-path (string-append %store-directory "/" store-item)))
      (values '((content-type . (text/x-nix-archive)))
              (lambda (port)
                (write-file store-path port)))))

Thoughts?
