matrixOS – Gentoo-Based Immutable Distribution with Atomic Upgrades
Quoting: matrixOS - Gentoo-Based Immutable Distribution with Atomic Upgrades - LinuxLinks —
matrixOS is a Gentoo-based distribution which combines Gentoo’s flexibility with an immutable base system and atomic updates. Rather than updating the running base installation package by package, matrixOS uses OSTree deployments. An upgrade is deployed as a complete filesystem state, allowing the system to retain an earlier deployment that can be selected if something goes wrong.
The distribution is primarily designed for desktop systems and homelab use. Its developers describe reliability and gaming support as its two main goals. Images are available with GNOME or System76’s COSMIC desktop, each maintained as a separate OSTree branch. Users can switch branches with the distribution’s vector management utility.
matrixOS includes current Mesa and NVIDIA graphics drivers and comes prepared for gaming with Steam and Lutris. Applications can also be installed using Flatpak and Snap, while Docker is available for containers. The underlying Gentoo environment and Portage remain important to how the system is built, but the normal matrixOS installation keeps the base operating system read-only.
