[yocto] ACPI powerbtn

[Jim Abernathy]

Okay, I found a solution that works for core-image-base for NUC.

1. create /etc/acpi/events/powerbtn

event=button[ /]power
action=/etc/acpi/powerbtn.sh

2. create /etc/acpi/powerbtn.sh

#!/bin/sh
# /etc/acpi/powerbtn.sh
# Initiates a shutdown when the power putton has been
# pressed.
/sbin/shutdown -h now "Power button pressed"

3. reboot

I need to add something that will 'shutdown -h now' when the power button is pressed.  I would figure that ACPI is already included in the core-image-base of the NUC bsp.

Do I need to include a new file in /etc/acpi/events or do I need to include some package?
I'm literally signing off for the day but for what it's worth core-image-sato does that already on my NUC, so there must be something in that image that makes it work...  maybe acpid or acpi-support isn't part of core-image-base?

I went back and built core-image-sato and the power button does nothing.  I don’t see anything in the /etc/acpi/events directory.  Same as core-image-base.
