OK, I've managed to find the problem.  rpc.mountd daemonizes itself upon
starting by default, which is not supported by Shepherd (at least not
its `make-forkexec-constructor' procedure).  I had to pass the
'--foreground' option to workaround this limitation (c.f.: commit
5fdc5b2d57d2e7ab04dbaf9c85e7f34eebe81495).

It'd be interesting to see what systemd does when a service is hinted as
forking in its configuration file.  We should also document that
limitation in the Shepherd info manual (see attached patch for
Shepherd).
