Powered by the Linux 5.8 kernel series, Fedora 33 is the first release to use Btrfs as default file system for all the official spins. Btrfs comes with some great features compared to the EXT file system, including copy-on-write, snapshots, transparent compression, checksums, pooling, and the ability to span over multiple hard drives. However, since Fedora 33 is the first release to switch to Btrfs by default, only some basic features were enabled in the file system, probably to make sure everyone has a stable and safe experience. Future Fedora Linux releases will enable more Btrfs features if they’re requested by the community.
