That keeps coming up.  I never said I was after anyone discarding their
hardware.  Use old hardware, use an old NUT version.  Or, more likely,
use the big clanking complicated steam-powered upper layer and drivers,
unlike the 99% of users who are using the zippy new zero-configuration 
spin of the code.

What does BSD use as a power-fail signal, then?
