# Several tests depend on RTC to wakeup from suspend. But on devices with dark
# resume enabled, powerd will suspend the device immediately on wake from RTC.
# This can interfere with the tests. Thus this script disables dark resume on
# test images. powerd gives highest precedence to settings under
# /var/lib/power_manager. Thus this overrides settings from other sources.
# Please look at power_manager/docs/faq.md#powerd-preferences for preference
# order. If a test intends to enable dark resume, it should create a temporary
# directory and mount it in place of /var/lib/power_manager and restart powerd.
