svctcp_create (and apparently svcudp_create, which seems to have no
manpage) takes as a parameter a value which can be a pre-prepared
socket, or the value RPC_ANYSOCK to have the routine create a socket.

However, the code re-binds the socket if one is passed, which rather
defeats the purpose, it seems to me.  (In particular, I wanted to add
code to mountd to make it listen on only one of the available
addresses, which means binding sockets before calling svc*_create, but
upon UTSLing I find this won't work.)

Is this deliberate?  Would it be worth submitting patches to change it?
Does anyone have any plausible scenario that would break if I moved the
binding of the socket inside the if (sock == RPC_ANYSOCK) conditional?
(Does anyone ever pass anything but RPC_ANYSOCK? :-)

Or does anyone have any better way to recommend to do what I want?
Running rpcinfo to find out what port is in use and dynamically
generating an ipf rule to match doesn't count. :-)
