Like I wrote earlier, ext4 is better tested configuration. For the people who take care of the release, believe me, it=E2=80=99s reassuring to= have one less moving piece. So the question is not whether Btrfs is =E2=80=9Cbetter=E2=80=9D, it=E2=80= =99s more about the confidence and peace of mind of those responsible for the release and subsequent maintenance. Now, contributions that make Btrfs well-supported in the installer (is anything missing there?) and in system tests would be welcome I guess. In the manual, it=E2=80=99s also fine IMO to mention something like: Some file systems, such as Btrfs, support compression, which is reported to nicely complement file deduplication that the daemon performs independently of the file system (@pxref{Invoking guix-daemon}). So a hint for savvy people rather than a recommendation. Ludo=E2=80=99.
