Bootc-based immutable OS images built on AlmaLinux, CentOS Stream, and Fedora
Tuna OS brings a modern cloud-native desktop to Enterprise Linux. We take the stability of AlmaLinux and CentOS Stream and layer on the latest GNOME, KDE Plasma, COSMIC, and Niri desktops — shipped as immutable bootc container images.
Inspired by Bluefin and the Universal Blue community.
| Image | Base | Description |
|---|---|---|
| yellowfin | AlmaLinux Kitten 10 | Closest to upstream CentOS Stream |
| albacore | AlmaLinux 10 | Stable Enterprise Linux base |
| skipjack | CentOS Stream 10 | Beta — upstream testing builds |
Every image ships multiple desktops (gnome, kde, cosmic, niri) and hardware variants (-hwe for newer kernels, -nvidia for NVIDIA/CUDA).
