This is OK. Though, in the specific case of output_openstack#precheck I'd still check for the existance of the "openstack" executable first, just like what Python_script.error_unless_python_interpreter_found does. This way there is a better error message to cover the case described in the commit message, even in case -v is not passed. -- Pino Toscano
