Powerd does not work in os9. Looks like a regression.
Apparently things have been moved around in /sys in the new build and powerd does not find
the files in the expected places
/var/log/powrd.trace says:
/usr/sbin/powerd: line 911: d: unbound variable
chmod: cannot access `/sys/class/backlight/dcon-bl/brightness': No such file or
