A subvolume is also a snapshotting barrier, so it's convenient to create subvolumes in well-known paths that contain data that should not be rolled back (/var/log, /srv, bootloader). -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
