Porteus-Kiosk 5.4.0 (x86_64) — Post

Porteus-Kiosk 5.4.0 is a lightweight, locked-down Linux distribution designed to run a single full-screen web browser on x86_64 hardware. It’s intended for kiosks, digital signage, public terminals, and other single-purpose systems where security, stability, and minimal maintenance are priorities.

Key features

  • Single-app kiosk mode: Boots directly into a full-screen browser (Chromium-based or Firefox ESR variant depending on build), preventing users from accessing the underlying OS.
  • Small footprint: Minimal kernel and userland components for fast boot and low resource use.
  • Read-only/immutable system: Designed to run from ISO, USB, or other removable media with optional persistence; reduces risk of tampering.
  • Customizable start page and session behavior: Configure homepage, default tab(s), homepage navigation, and kiosk session parameters.
  • Auto-recovery and watchdog options: Auto-restart on crashes or network failures; options for restoring a clean state on reboot.
  • Remote management support: Options for remote updates or management via preconfigured scripts or services (varies by build).
  • Hardware compatibility: Supports most x86_64 hardware, with minimal drivers included; works well on older or low-powered machines.

Kernel Hardening

The 5.4.0 kernel has modules like CONFIG_SECURITY_SELINUX and CONFIG_STRICT_DEVMEM disabled by default, but the Porteus team applies grsecurity-like patches. The /proc/sys/kernel protections prevent common Linux breakouts. Porteus-Kiosk-5.4.0-x86-64.iso
