For what it is worth, the cause of this bug was that the creation of static device nodes (including /dev/btrfs-control) moved from systemd-udevd to systemd-tmpfiles, but we forgot to add a call to tmpfiles in the udev hook. This has now been fixed and the systemd in testing should work with btrfs without the need for adding any modules manually. Cheers, Tom
