How do these indicate failure to the test runner? Is the output parsed?

If output is parsed, this says FAILURE, and so will probably trigger a failure. Either way, this message can probably be cleaned up.

Same, here, this message should probably not say FAILURE in is. Maybe "SUCCESS - v4.0 mount correctly rejected" or something?
