   Good question @patacongo I don't get it too :-) 
   
   Could you please elaborate more on your goal @fxysunshine ?
   
   In Unix if you want to provide different applications with a separate access levels (i.e. to filesystem), for instance when you run a service, you would want to create a dedicated user and group for that application (or group of applications), then launch that application by that user/group. Services may be launched by system init scripts and/or local user crontab. Not sure if all this functionality is already here in NuttX?
   
   The problem you are facing right now is that UID/GID is not set even if you run the application by a given user?
   
   Maybe you want something like `su` to run one application as another user?
   
   Maybe you want `setuid`/`setgid` functionality in order to spawn process with `uid`/`gid` or a file owner?
