The fifo_zlogin service, is a new minimalistic service introduced with the 0.7.1 release. It is a service that compliments and enhances the Chunter service and is now a required dependency for running Chunter.
One of the primary purposes of the FiFo Zlogin is for Docker support. Some Docker commands require that a STDIn and STDOut to the zone remain opened - if that gets closed the whole thing shuts down. This, of course, is sub-optimal as we don't want all Docker zones getting shut down every time there is a Chunter update.
To address this problem, a FiFo Zlogin service was introduced to ensure the IO is kept open so that Chunter can be upgraded without IO being affected.
