Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hello list, Nowdays, external hard drives are mounted automagically by kde, gnome or whatever else. How is it suppose to work with external hard drives using btrfs with compression? If a btrfs filesystem lzo-compressed is mounted without the |compress=|xxx option then all the newly created files are uncompressed, aren't then? Would it be possible to detect if a file system is compressed and to mount it *automatically* and accordingly (except otherwise explicitly stated by the user) with/without the lzo/gzip option? Xavier
