Welcome to TunaOS

Modern Cloud-Native Enterprise Linux

TunaOS is a set of desktop operating systems that use Bootc. Enterprise Linux 10 is the base: AlmaLinux and CentOS Stream. TunaOS is a fork of Bluefin LTS for the next generation of enterprise desktops.

Enterprise Linux gives stability and long-term support. Developers and workstation users also need new tools. TunaOS supplies both.

✨ Why TunaOS?

• 🖥️ Latest GNOME: The gnome50 image adds GNOME 50 to Enterprise Linux. You get the newest desktop features and the stable distribution GNOME. The system stays stable.
• 🍺 Baked-in Homebrew: Homebrew is installed. You get immediate access to a large library of command-line tools and fonts.
• 📦 Bootc Technology: Modern container technology makes the system immutable, reliable, and easy to reproduce.
• 🏢 Enterprise DNA: AlmaLinux 10 and CentOS 10 are the base. Support continues for as many as 10 years.
• 🛍️ Flathub Enabled: Flathub is on at installation. A full set of desktop applications is available immediately.

🧰 Beyond the OS

TunaOS is more than its images. It is a set of tools that build the images, install them, and distribute them:

• Tacklebox — makes multi-boot USB drives, disk images, and deduplicated ISOs from OCI images.
• Tromsø (KDE), XFCE Linux, and Dakota (GNOME) — "distroless" desktops. A declarative BuildStream pipeline makes them on top of the Freedesktop SDK.
• COPR Builds — the RPM build system. It adds GNOME 50 to EL10.
• Tavern and bluefin-cli — tools for the desktop and the shell.
