How would I go about moving the mount daemeon to a reserved port??
Specify port/protocol in /etc/services, example stupidly sets port 80: "mount 80/udp # rpc-mountd on custom port", or use startup param --port.


How would I even find out which ports ARE reserved!?!?
Ports 0-1024 are the reserved ports. It means to processes is that only processes started by the root account user are allowed to bind to a port below 1024. What that means to you as remote user is that you have a very weak guarantee a process on a port below 1024 is vaguely safe (IOW: no real guarantee at all).

What affect (if any) will this have on the box??
It will not enhance security and the human root account owner's hair will fall out.
