I haven't done the research myself, but the result was that pax would have needed significant extension, but I don't have the details. If you dig out a format already in use that supports everything we need (like sharing data between files, needed for btrfs reflinks), it should be easy to change the format. Stuffing the data into a specific format is not an essential part of the work and can be changed with a limited amount of work. -Arne > Irek _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
