Someone Just Made an Immutable Gentoo-Based Distro Tailored for Gaming

matrixOS is a new immutable, atomic Linux distribution based on Gentoo, created by the original Sabayon Linux developer. It uses OSTree for atomic upgrades and follows an "emerge once, deploy everywhere" philosophy, building packages once and distributing binaries to avoid repeated compilation. The distro targets gaming and homelab setups with pre-configured Mesa and NVIDIA drivers, SecureBoot support, btrfs filesystem with zstd compression, and includes Steam, Docker, Flatpak, and Snap out of the box. Available in three variants (Bedrock, GNOME, and Server), it requires UEFI to boot and is currently a hobby project not intended for production use.
