At no point does the author elaborate on why failing to start if the environment isn&#x27;t sane is a bad thing. All my software checks for the things it expects to be in place, then bails hard and fast if they aren&#x27;t.<p>It&#x27;s then up to the init daemon to attempt to restart that process, and up to the monitoring and orchestration tools to ensure that the environment returns to sanity over time.
