  • Page 17: Overlayfs

    4.4. OverlayFS The BrioSens™ uses a read-only filesystem to prevent changes from occurring on the root filesystem that may corrupt the system. It allows a simple reboot to restore a system to a pristine state. BrioSens™ uses OverlayFS to allow temporary modification of read-only files and folder.

  • Page 18: Customizing The File System

    4.6. Customizing the file system Modifying the file system may corrupt the system. If the BrioSens™ Gateway stops working after customizing the file system, simply revert the changes by using a file system provided by Briowireless. Once customized and updated, the file system will become read-only and any changes to that file system will be restored with a reboot.
