Also move the @cindex line after @subsubheading.

This procedure no longer exists.  :-)

So instead, you need to add an @defvr for ‘rpcbind-service-type’ and an
@deftp for ‘rpcbind-configuration’, and a couple of sentences to glues
them together (see “Scheduled Job Execution” for an example.)

Better use ‘shepherd-service-type’ here, as noted at
<https://lists.gnu.org/archive/html/guix-devel/2016-09/msg00271.html>.

And then we’re done.  Could you send an updated patch?

Thank you for your patience!
