  # (performed by script tools/setup-buildbot-device.sh) before the
  # "device cleanup" step (implemented by this script). As
  # property_contexts file aliases are created during the former step,
  # we need this exception to prevent the property_contexts file under
  # /system in the chroot from being removed by the latter step.

  # before "setup device" and remove this special case.

  # TODO: Also consider adding a "tear down device" step on the ART
  # Buildbot (at the very end of a build) undoing (some of) the work
  # done in the "device setup" step.
