- * OFF:
- * - OFF means that the OS is still initializing. Initialization is very fast so
- *   if you see this at all, it probably means that the system is hanging up
- *   somewhere in the initialization phases.
- *
- * GREEN or GREEN-ish
- * - This means that the OS completed initialization.
- *
- * Bluish:
- * - Whenever and interrupt or signal handler is entered, the BLUE LED is
- *   illuminated and extinguished when the interrupt or signal handler exits.
- *   This will add a BLUE-ish tinge to the LED.
- *
- * Redish:
- * - If a recovered assertion occurs, the RED component will be illuminated
- *   briefly while the assertion is handled.  You will probably never see this.
- *
- * Flashing RED:
- * - In the event of a fatal crash, the BLUE and GREEN components will be
- *   extinguished and the RED component will FLASH at a 2Hz rate.
