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.
