DISABLE_OPEN_TOOLS- If set, disablesxdg-openandexo-openbinaries by removing their execute permissions.DISABLE_SUDO- If set, disables thesudocommand by removing its execute permissions and invalidating the passwordless sudo configuration.DISABLE_TERMINALS- If set, disables common terminal emulators by removing their execute permissions and hiding them from the Openbox right-click menu.DISABLE_CLOSE_BUTTON- If set, removes the close button from window title bars in the Openbox window manager.DISABLE_MOUSE_BUTTONS- If set, disables the right-click and middle-click context menus and actions within the Openbox window manager.HARDEN_KEYBINDS- If set, disables default Openbox keybinds that can bypass other hardening options (e.g.,Alt+F4to close windows,Alt+Escapeto show the root menu).RESTART_APP- If set, enables a watchdog service that automatically restarts the main application if it is closed. The user's autostart script is made read-only and root owned to prevent tampering.This allows single app containers to be locked to the app, when passing like
-e HARDEN_DESKTOP=trueand-e HARDEN_OPENBOX=trueto a container it becomes a single app instance that the client really cannot change anything about the container just stay in the app sandbox.example :
This all depends on the app but stuff like chromium uses xdg-open to open files or file managers so it really is isolated down to its base function and cannot spin up random bins from its file:// url scheme. Even extensions would be forced to use that standardized api as far as I understand it.
