The problem with trying to get the same port for all tcp/udp/inet/inet6
though might succeed most of the time, will fail sometimes, then what?
I saw Doug's commnent, and also the :), it's not as simple as tracking port
80 or 25, needs some efford, but it's deterministic/programable, and worst case
you can still use the -p option (which again will fail sometimes :-).

IMHO, having a system that might fail to reboot is not very pleasant.
