mountd can and should use a dynamic port assignment, IMO.
It doesn't have to use 20048.
Speaking of 20048, does anyone know why Nico made this assignment?
Apart from making it well-known for firewalls, what system(s)
actually required it? I don't recall it ever being discussed.
Using it is certainly not required, since portmap resolves it.

Actually my first active interaction with the nfsv4 WG was at the
IETF meeting in Montreal in late July of 2010. So I can't say that
I have any memory of why this was done. It might be a question that
can be answered by someone on nfsv4@xxxxxxxx.
Sure, or Nico directly. What I was wondering is why nfs-utils seems
to have implemented it? Surely there was a reason?
