That file is a bit old, it hasn't been updated since 2009 - While it might not be production-ready, it's not as bad as it does sound (for example, the disk format is finalized, and shouldn't get any changes in the future). Something a bit more up to date (but still a bit old) can be found on the btrfs wiki: https://btrfs.wiki.kernel.org/index.php/FAQ#Is_btrfs_stable.3F https://btrfs.wiki.kernel.org/index.php/FAQ#Is_btrfs_stable.... and https://btrfs.wiki.kernel.org/index.php/Main_Page#Stability_status https://btrfs.wiki.kernel.org/index.php/Main_Page#Stability_... As for the distros, I think none of the big ones default to it yet, but it's definitely a first-class citizen in OpenSUSE (and should be the default fs in OpenSUSE 13.2, according to the official plains).
