Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting Approved by: re
