The bcachefs file system, now "externally maintained" outside the Linux kernel codebase, offers packages of its first version to be loadable on the fly.
The development of bcachefs has been officially jettisoned from that of the Linux kernel itself. At present, the work-in-progress kernel 6.17 still contains bcachefs code, but unmodified from the 6.16 release. In response, the project has published its first set of packages of a version that can be dynamically loaded as a DKMS module, as promised a couple of weeks ago in an email from project lead Kent Overstreet.
It's available as an APT repository, which for the time being limits it to Ubuntu and Debian-based distros.
