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.

HISTORY
Support for the power
driver first
appeared in OpenBSD 4.1.
