Two of the links under
<http://open-zfs.org/> is outdated. Instead:
<http://docs.oracle.com/cd/E19253-01/819-5461/index.html> no longer appears as it should; <https://discord.com/channels/727023752348434432/760416197803245591/868506932539965530> – given the FreeBSD focus on OpenZFS, I reckon that it's safe to discard the link to Oracle's documentation.
