  "message": "update_engine: Process Omaha response for rollback images\n\nOmaha returns whether the image returned is a rollback in the\n_rollback\u003d\"true\" argument. If this is set, the client has to check\nwhether it\u0027s OK to apply the rollback image (policy is specifically\nrequesting a rollback and verified boot will accept the image based\non its kernel and firmware key versions).\n\nIn addition to this, the device has to do a safe powerwash if the\nimage is a rollback. (We\u0027re not supporting rollbacks with partial\nor no powerwash yet.)\n\nWe\u0027re also setting the rollback_happened preference to avoid force\nupdates happening before the policy is available again.\n\nChromium CL adding the error code: http://crrev.com/c/1047866\n\nBUG\u003dchromium:840432\nTEST\u003d\u0027cros_run_unit_tests --board\u003dcaroline --packages update_engine\u0027\n\nChange-Id: I1436ca96211b2a8523e78bf83602ef8b6b525570\nReviewed-on: https://chromium-review.googlesource.com/1047610\nCommit-Ready: Marton Hunyady \u003chunyadym@chromium.org\u003e\nTested-by: Marton Hunyady \u003chunyadym@chromium.org\u003e\nReviewed-by: Amin Hassani \u003cahassani@chromium.org\u003e\n",
