AFAIK, the FreeBSD 11.0 installer wants the whole disk if I choose:

     Partitioning                    Auto (ZFS)

My solution was to buy a 16 GB SSD.  Once installed, I moved the image 
onto a larger drive.  This seems to work with just a basic install. 
(Previous attempts to move an image with Xfce resulted in broken Xfce.)
