[...a slight aside...]
I also have a box at home with embedded LEDs and an LCD display and what
I found most useful was the following:
(0) At poweron, the LED is red by default (the hardware does
(1) On driver init, the LED goes into reg/green blink at some
rate (it's a two-color LED obviously :-) to indicate it's
still doing autoconfiguration and the like.
(2) Early in the rc sequence, I set the LED to solid green so
I can tell it's reached userland.
(3) On shutdown, I set it to blinking red once it's OK to power
Step (2) is just done via 'echo <stuff to turn it green> > /dev/led';
steps (1) and (3) are done by the kernel, obviously.
