New versions of the Kiosk systems are out. These systems update official Nerves systems with a local web browser for rendering user interfaces.
The following kiosk system updates align with the v1.9.0 Nerves system releases for the Raspberry Pi and x86_64.
Work is moving forward for kiosk support on Raspberry Pi 4. The initial commits for this repository can be tracked at: https://github.com/LeToteTeam/kiosk_system_rpi4. This system boots but additional project configuration is required to get QT to render.
