[Sabayon Linux](https://en.wikipedia.org/wiki/Sabayon%5FLinux?ref=itsfoss.com) was a Gentoo-based distribution that existed from the mid-2000s until 2019\. It aimed to make Gentoo accessible to regular users without the usual compilation headaches.

Created by [Fabio Erculiani](https://www.linkedin.com/in/fabio-erculiani-b154b74/?ref=itsfoss.com), Sabayon offered pre-built binaries through its Entropy package manager. This let users skip the hours of compiling while still getting the Gentoo experience.

Now Fabio [has shared](https://www.phoronix.com/news/Sabayon-Linux-To-matrixOS?ref=itsfoss.com) that he's working on a new immutable, atomic Linux distro called **matrixOS**. Like Sabayon, it's also based on Gentoo.

🚧

**The developer warns that this is* ***a hobby project** *specifically created for* [**homelab*](https://itsfoss.com/tag/homelab/) *setups, not for production machines.*

## matrixOS: Overview ⭐

The project's motto is "*emerge once, deploy everywhere*." In Gentoo, [emerge](https://wiki.gentoo.org/wiki/Emerge?ref=itsfoss.com) compiles packages from source on practically every machine you set up. matrixOS remedies this by building once and distributing binaries, so you skip the compilation wait entirely.

Plus, it uses [OSTree](https://ostreedev.github.io/ostree/?ref=itsfoss.com) for atomic upgrades. Your system either updates completely or not at all. **The base is read-only**, which prevents accidental breakage.

Gaming is also one of its priorities, with the latest [Mesa](https://mesa3d.org/?ref=itsfoss.com) and [NVIDIA](https://www.nvidia.com/en-us/drivers/?ref=itsfoss.com) drivers handling AMD and NVIDIA GPUs, so graphics work right away without you needing to go looking for drivers.

Cooling management is handled by [coolercontrold](https://docs.coolercontrol.org/?ref=itsfoss.com) and [liquidctl](https://github.com/liquidctl/liquidctl?ref=itsfoss.com), and the filesystem runs btrfs on both `/boot` and `root` with zstd compression. The root partition auto-resizes on first boot and NTFS drives work using the [NTFSPlus](https://itsfoss.com/ntfsplus/) driver.

**SecureBoot support is built in** with certificates you can enroll directly in UEFI BIOS or through Shim MOK enrollment at first boot.

Looking ahead, the project aims to implement proper CI/CD pipelines and testing workflows, rewrite the core tooling in Go (*replacing the current bash scripts*), and migrate to [bootc](https://bootc-dev.github.io/bootc/?ref=itsfoss.com) or build a wrapper on top of OSTree with [Unified Kernel Image](https://uapi-group.org/specifications/specs/unified%5Fkernel%5Fimage/?ref=itsfoss.com) (UKI) support.

## A Quick Look 😶‍🌫️

**matrixOS' GNOME implementation looks slick.*

Seeing that matrixOS is an experimental distro, I ran it as a virtual machine using [Virtual Machine Manager](https://virt-manager.org/?ref=itsfoss.com). Right away, I found the GNOME interface familiar, but with a Windows-like taskbar at the bottom.

I could access pinned apps, notifications, and the quick-settings menu from here, with a handy button on the far-right letting me focus on the desktop when multiple app windows were open.

**Speaking of apps**, there are plenty of useful ones included, like [Steam](https://store.steampowered.com/?ref=itsfoss.com) for gaming, [Btop](https://www.youtube.com/watch?v=ZXClWDkOH3Q&ref=itsfoss.com) for system monitoring, [Google Chrome](https://www.google.com/chrome/?ref=itsfoss.com) for browsing, and [gedit](https://itsfoss.com/gedit-tweaks/) for text editing. Classic games like Mahjong and Chess are also pre-installed.

Likewise, the distro ships with [Google Antigravity](https://antigravity.google/?ref=itsfoss.com) for AI-assisted coding, and there's built-in support for [GNOME Shell extensions](https://itsfoss.com/gnome-shell-extensions/) if you want to further customize the desktop to your liking.

**matrixOS gives you many ways to install new apps!*

*Flatpak*, *Snap*, and *Docker* **are all pre-configured and ready to use**, so you have multiple options for installing apps. GNOME Software ties it all together with a simple interface for browsing and fetching applications without [you needing to touch the terminal](https://itsfoss.com/no-longer-need-terminal/).

matrixOS comes in [three variants](https://images.matrixos.org/index.html?ref=itsfoss.com): *Bedrock*, *GNOME*, and *Server*. Each is available in `raw` for flashing to drives and `qcow2` for running on [virtual machines](https://itsfoss.com/virtual-machine/).

The distro **requires UEFI to boot**, so legacy BIOS systems won't work. For logging in, the default password is "*matrix*," and the source code lives on [GitHub](https://github.com/lxnay/matrixos?ref=itsfoss.com) for people interested in contributing or building from source.
