The events will appear on /dev/devctl and can be parsed by devd. If you can do what you want via devd.conf, fine. If you want to have your own program reading /dev/devctl, you'll have to implement device cloning for /dev/devctl first or not run devd. (A current deficiently in devctl is that only one reader can be present at a time.) -Nate
