I think that it would be nice if the installer has the option to set a 
feature like this to off. Is it easy to break out of the installer, 
create the pool before hand and use that pool?

      Hi,<br>
      <br>
      When you create a new pool you can use something like this:<br>
      zpool create -o feature@block_cloning=disabled ...<br>
      <br>
      I tried setting this on an existing pool. That gave me an error.<br>
      # zpool set feature@block_cloning=disabled zdata4<br>
      cannot set property for 'zdata4': property 'feature@block_cloning'
      can only be set to 'disabled' at creation time<br>
      <br>
      So to install a new 14.2 system you need to do some manual work to
      create the root pool with the options you prefer.<br>
      <br>
