Fedora Atomic Desktops (Silverblue, Kinoite, and others) are immutable Fedora variants where the base OS is read-only and updated atomically via rpm-ostree. Applications run as Flatpaks, and rollback to a prior OS image is built in.

Our take
Immutability changes the threat model in a meaningful way: a compromised package or a bad system update cannot silently alter the base OS, and rolling back is a single command rather than a reinstall. Fedora’s position close to upstream and Red Hat’s engineering backing means SELinux is on by default and the tooling is polished. The honest friction point is the Flatpak-centric workflow - traditional RPM package installs go into layered overlays that complicate the image, so this design suits users willing to embrace Flatpak or containers. A natural upgrade path for anyone on standard Fedora Workstation who wants more resilience without leaving the ecosystem.
