# This is a helper script for testing an in place rollback.
# It doesn't change the image, it initiates all the state
# saving, then triggers a powerwash and reboot. When the device
# reboots it will be in the state as if it was rolled back to
# the current version.
#
# This script isn't intended to be shipped on the device, it's
# only for manual testing.
