power — power
switch
power0 at obio?
Landisk models provide an interrupt when the power switch is
flipped to the Off position. The power driver
catches that interrupt. If the hw.allowpowerdown
sysctl(8) is set to 1,
power will signal
init(8) to do a clean shutdown.
Support for the power driver first
appeared in OpenBSD 4.1.
