 Chef Client will only exit with exit codes defined in RFC 062.  This allows other tooling to respond to how a Chef run completes.  Attempting to exit Chef Client with an unsupported exit code (either via `Chef::Application.fatal!` or `Chef::Application.exit!`) will result in an exit code of 1 (GENERIC_FAILURE) and a warning in the event log.
