Hello Jon, Any script in rc.local is probably called by root, so it's best to 
follow the example of NUT itself and drop to a non-privileged with something 

  sudo -u nut /usr/local/bin/reboot_notify

This list is relaxed about top posting versus bottom posting, but as you venture 
futher into the Linux world, you will meet lists which expect bottom posting, so 
it's helpful to get into the habit.
