Following up to myself, I cooked the following script to be placed in /etc/rc.d/, it works fine and does what I want it to do. Maybe it helps someone else to save time to accomplish the same thing. Now I just wonder whether it would be more elegant to place a script that does the actual work in /usr/local/bin and just launch that one from a small script in /etc/rc.d/. I suppose it's a matter of taste. Oh - does stuff like this merit submission to ports?
