I have checked this update for mountd in 10-CURRENT and has two questions:

1. What is the sense to try to use the same port number for all
   supported netconfigs if specific port number is not given in
   a command line option?

2. What is the sense of specifying specific IP addresses for mountd and
   similar RPC programs that do not have predefined port numbers?

One comment for netconfig related functions usage.  Each setnetconfig()
call allocates memory and depending on implementation can use other
resources, so endnetconfig() should be called before reusing netconfig
handle.
