The zpool and zfs commands do everything through ioctls, and /dev/zfs is the device node those ioctls are bound to. You can't read from it or write to it; all you can with /dev/zfs is use ZFS's custom ioctls. -Alan _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
