Cloud-native, immutable desktop Linux images​

One bootc-native desktop experience across Enterprise Linux and community distributions

About TunaOS​

TunaOS builds bootc-based desktop operating systems with atomic updates and straightforward rollbacks. Choose an Enterprise Linux base for long-term stability or a community distribution for a faster release cadence, while keeping the same image-based management model.

Visit tunaos.org or read the launch announcement.

  • Modern Desktops: GNOME, KDE Plasma, COSMIC, Niri, and XFCE — equal first-class options across distribution bases
  • Up-to-Date Desktop Stack: Fresh desktop features and updates backported to Enterprise and community bases
  • Homebrew: Baked into the image — all your CLI apps and fonts are just a brew command away
  • Flathub by Default: Full Flathub access out of the box — get any Flatpak available on the net
  • HWE and NVIDIA Options: Hardware Enablement kernels and NVIDIA drivers + CUDA as image tags

Tags are <desktop>[-hardware] — e.g. yellowfin:gnome-hwe, albacore:kde-nvidia. Full tag reference: docs/IMAGE-TAGS.md. Hardware requirements and ARM laptop status: docs/HARDWARE.md.

[!NOTE] Redfin (RHEL 10) is local-build only due to EULA restrictions. To build it locally, run just build redfin <desktop> (see rhel-setup.md).

Live build matrix​

Generated from the latest conclusive main-branch build for each variant (cancelled runs are skipped over). A cell is green when its image was successfully promoted to the published tag; failing means a job ran and failed; not reached means no job asserted the cell at all, usually because an earlier stage stopped it.

Built 75/142 · composite green 75/142 (52%) — of the remainder, 0 failing and 67 never reached (no job asserted them). The two are reported separately on purpose: a never-reached cell is untested, not broken. Composite green is scored against .github/green-criteria.yml (blocking today: builds + boots — a cell must promote AND pass its boot Gate; the full per-axis board is docs/MATRIX-STATUS.md). This is a point-in-time CI snapshot, not a support-tier promise.
