Fedora Hummingbird is a new container-based rolling Linux distribution announced at Red Hat Summit 2026. It extends Project Hummingbird's zero-CVE container image philosophy to the full host OS, delivering the entire Linux system as an OCI image built with a Konflux pipeline, hermetic RPM-locking, and continuous vulnerability scanning via Syft and Grype. The OS uses atomic updates with rollback support, a read-only root filesystem, and the ARK kernel tracking Linus' mainline. Built on Fedora Rawhide packages, it supports x86_64 and aarch64, and can run in VMs or on bare metal. The project is open for community contribution with no registration or subscription required, and the team aims to formally integrate it into the Fedora Project.
