Put the info in the HowTo Wiki, Dude! And Thanks!

Oh, for all who might not know what the 'long press' of the power button is. When you press the power button of a linux device which is turned on it does an 'orderly' shutdown, of the kind that you want to do most of the time. When you hold the power button down for more than 5 seconds it bypasses the code for an orderly shutdown and stops the device cold, in a way you usually want to avoid. Yes, there are exceptions, as noted here.
