Thanks. It looks like this might be the way to go, but my initial
attempts haven't gone far. I'll keep looking around.

One thing that I have a question about still is the output from udev:

# /etc/init.d/udev restart
Stopping the hotplug events dispatcher: systemd-udevd.
Starting the hotplug events dispatcher: systemd-udevdstarting version 233

Is a udev restart enough to reload? How much systemd is in there?
