I think r1.34 was changed to attach zfs volumes automatically: if (((!strcmp(mnt.mnt_fstype, "ufs") && !strcmp(mnt.mnt_fstype, "zfs"))) This is always false. The source of this patch (rt #56531) is bogus so I guess that ticket should be updated. I assume it should be if ((!(strcmp(mnt.mnt_fstype, "ufs") && strcmp(mnt.mnt_fstype, "zfs"))) -frank
