Executive Summary

Porteus Kiosk 5.4.0 is a specialized, lightweight Linux distribution designed for a single purpose: to turn a computer into a secure, single-use web appliance. Unlike standard desktop Linux distributions, it locks the user into a web browser session, preventing access to the underlying operating system, settings, or files.

• The Lockdown: The user cannot minimize the browser, access a terminal, right-click the desktop, or switch TTYs (virtual consoles). The system effectively becomes a kiosk machine.
• Read-Only Filesystem: The root filesystem is mounted as read-only. Every time the system reboots, it returns to a pristine state. Any temporary downloads, cache, or history from a user session is wiped instantly. This is the "Holly Grail" for public computing hygiene.

• Kernel Update: It ships with a modern Long-Term Support (LTS) kernel (typically the 5.15.x or 6.1.x series depending on the specific build time), ensuring support for modern WiFi chips and graphics cards.
• Browser Choice: It supports the latest stable versions of Firefox and Chrome. This is critical, as web standards evolve quickly.
• Hardware Support: Improved support for modern GPU architectures (Intel/AMD/Nvidia) ensures smooth video playback and HTML5 rendering, which is vital for digital signage.

Security: Includes support for importing DER certificates via the import_certificates= parameter and blocks system-default key combinations even when using secondary keyboard layouts. Porteus-Kiosk-5.4.0-x86-64.iso
