NAME #

power - power switch

SYNOPSIS #

power0 at obio?

DESCRIPTION #

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.
