        AUTO LOAD ENABLED
        AUTO PERM ENABLED
        EXCLUDE = (*)
        INCLUDE = (TX, DN)

      In this example, all devices are excluded with the exception
      of TX and DN devices. A joystick using AGA0, for example, will
      not be configured, but a disk DNA0 will be configured, as will
      TXC2.
