* In the event of failure, a key of 'failed' should be included, along with a string explanation in 'msg'. Modules that raise tracebacks (stacktraces) are generally considered 'poor' modules, though Ansible can deal with these returns and will automatically convert anything unparseable into a failed result. If you are using the AnsibleModule common Python code, the 'failed' element will be included for you automatically when you call 'fail_json'.
* Return codes from modules are not actually not significant, but continue on with 0=success and non-zero=failure for reasons of future proofing.

* As results from many hosts will be aggregated at once, modules should return only relevant output. Returning the entire contents of a log file is generally bad form.
