When Pebble performs a (potentially invasive or long-running) operation such as starting or stopping a service, it records a "change" object with one or more "tasks" in it.
The daemon records this state in a JSON file on disk at $PEBBLE/.pebble.state.
If the environment variable PEBBLE_PERSIST is set to "never", Pebble will only keep the state in memory without persisting it to a file.
