RakuOS is an immutable Linux distribution based on Fedora, with a choice of KDE Plasma, GNOME and COSMIC desktops. It combines an immutable, read-only base system with the full package flexibility of a traditional Linux distribution. While the core system updates atomically and can be instantly rolled back, the system's persistent overlay lets the user install any package, either through the dnf package manager or the distribution's own software center called RakuOS Software. Installation of Flatpak packages is also supported. RakuOS uses the performance-optimised CachyOS Linux kernel and also includes a graphical CPU scheduling utility to fine-tune the system for gaming, workloads or power efficiency use cases.
