I've just checked, it's around there at least since FreeBSD 2.0.5. The man page still lies that it were not implemented though... but i cannot remember a single feedback whether it's actually working now. It has been implemented blindly after the SCSI-2 specs by Julian Elischer. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
