<message>Modify the first-boot configuration to include the gir1.2-gtklayershell-0.1 package for improved GTK layer shell support. Update the first-boot script to enhance the portal status reporting with connection timeouts. Additionally, implement a restart mechanism for the kanshi service in rotation scripts to ensure immediate application of configuration changes. Introduce a Chromium kiosk extension to disable text selection, improving user experience in kiosk mode. These changes streamline the setup process and enhance the overall functionality of the kiosk environment.
