Another common element is that with each change your network interface goes down
and comes back up.

You're running Ubuntu right?  /etc/network/ifup.d (from memory, I'm at work and
there's nothing but Solaris and Windows around me) contains scripts that are
executed whenever the network interface comes up.  If you include your ln ...
command in one there the linking would happen automagically evertime the interface
came up, no matter where you were.

That thought "I need to automate the process somehow."  That's a good one.  Hold
on to it.  Great attitude to take.
