Hybrid Atomic Linux

RakuOS

Atomic Linux that doesn’t take away your package manager.

Immutable base. Install anything. Native gaming. Zero compromises.

Built on Fedora • Powered by bootc • CachyOS Performance Kernel
What is Hybrid Atomic?

Immutable base. Total freedom.

Traditional atomic Linux systems force a painful trade-off: keep the system immutable, or layer packages slowly with rpm-ostree or simular. RakuOS removes that compromise entirely.

RakuOS uses a persistent overlay system mounted directly on /usr. Your base system is always pristine — but you can install any native package you want, and it survives every system update.

Immutable base system with instant bootc rollback
Native packages persist across updates automatically
Works with dnf, dnf5, or RakuOS Software Center
One-command reset restores a pristine system instantly
Flatpak for sandboxed apps, native packages for everything else
Install anything. The way Linux always worked.
$ sudo dnf install steam
→ Installs directly into the persistent overlay
$ rakuos install lutris heroic-games-launcher
→ Multi-package overlay install
$ rakuos update
→ Updates base image via bootc, overlay packages auto-upgrade
Or just open RakuOS Software Center and click Install — it all goes to the same place.
Why RakuOS?

What other atomic distros got wrong. Fixed.

RakuOS was built by solving real frustrations with existing atomic Linux distros.

📦
No More Layering Hell

rpm-ostree layering is painfully slow and breaks after major updates. RakuOS replaces it entirely with a fast persistent overlay — packages install in seconds and survive every update automatically.

🛡️
Unbreakable Base

Your base system is always immutable and recoverable. A bad update? Boot into the previous image instantly with bootc rollback. Overlay packages stay intact either way.

🖥️
GUI Package Management

RakuOS Software Center works natively with the overlay. Browse and install native packages from a full GUI — no terminal required.

🎮
Native Gaming. Not Flatpak.

Steam, Lutris, and Heroic Launcher install natively for maximum Proton and Wine compatibility. Native packages outperform Flatpak for gaming — now possible on an atomic distro.

Fast Boot. Always.

Overlay mounts in milliseconds during early boot — before the login manager even starts. Installed packages are available immediately.

♻️
Instant Reset

Want a clean system? Wipe the overlay and reboot — your OS returns to pristine state instantly.
