Three weeks ago we reported that Red Hat would be dropping support for the Btr file system in future releass of Red Hat Enterprise Linux. This move raised some questions about the status of the file system and whether this would affect SUSE's distribution. SUSE Linux Enterprise (SLE) uses Btrfs as the default root file system and features tools for working with Btrfs features. A blog post on the SUSE website makes it clear the distribution will continue to work on Btrfs and support the advanced file system: "This year, we introduced the SUSE Container as a Service Platform and SUSE MicroOS with 'Transactional Updates'. As the host filesystem for container deployments on this platform we are supporting Btrfs, using a native Btrfs driver in the container engine, that is without the need for an overlay filesystem inbetween container and host, and thus improving the space efficiency when storing containers - flat and layered. And there is more to come: We just start to see the opportunities from subvolume quotas when managing Quality of Service (QoS) on the storage level. Compression (already there) combined with Encryption (future) makes Btrfs an interesting choice for embedded systems and IoT, as may the full use of send-receive for managing system patches and updates to (Linux based) 'firmware'. You see, SUSE is leveraging its expertise and investing on what matters for enterprise readiness, a field where Btrfs has proven in real life to be a great technology over the years, and we go, where open source technology drives innovation."
