Digital Signage & Kiosk Fleet Deployment Guide

TunaOS gives fleet administrators a container-managed base image for signage screens and interactive kiosks that run without an operator present.

Key Advantages for Kiosk & Signage Fleets​

  1. Resistant to Power Loss: The core system files in /usr are read-only. Nothing writes to them, so a sudden power cut does not leave a system binary half-written. The writable areas such as /var can still take damage. A power cut in the middle of an update can still stop the next boot.
  2. Central Fleet Management with OCI: Push a new container tag to a standard registry. Every screen picks it up on its next scheduled update.
  3. Single-App Kiosk Isolation: Run one full-screen application in an unprivileged container sandbox at start-up. Use Chromium, MPV, or your own web app.

System Configuration Highlights​

  • Desktop Baseline: A light TunaOS variant such as XFCE Linux or Bonito Niri. Set it to log in on its own with no desktop shell.
  • Kiosk Launch: Start the browser full-screen: 
    flatpak run org.chromium.Chromium --kiosk --incognito https://signage.internal.company.com
  • Unattended Updates: A systemd timer that runs bootc update in the quiet hours of the night.
