I must disagree here. libzfs API is for ZFS internal use only and is subject to change at any time. This is true for OpenSolaris as well. We, of course, can bump __FreeBSD_version if it helps, but one shouldn't expect libzfs API being stable or there is any care taken to maintain backward compatibility. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
