Because everyone is confused between the MOS file system...and MOS the RTOS...MOS can be any dedicated IC specific application...that utilizes specific portions of the full stand alone MOS RTOS.
MOS the RTOS...manages that special Protocol and configurations....and IMO... the optionally stored Protocol to open up different degrees of access through the authenticator...are stored in MOS proprietary file structures...utilizing it`s methods of security...there would be no reason to utilize anything else with regard to the special for the content management protocols.
