   ## pool locations
   
   One can add disks or parts of disks into pools.  Methods of specifying
   areas to be included include:
   
     - entire disks (e.g., /dev/rwd0d on amd64)
     - disklabel partitions (e.g., /dev/sd0e)
     - wedges (e.g., /dev/dk0)

   ## zvol
   
   Within a ZFS pool, the standard approach is to have file systems, but
   one can also create a zvol, which is a block device of a certain size.
   
   \todo The zvol will appear as /dev/???? and can be used in many
   respects like a slice.  However, the system will not read disklabels
   and gpt labels from a zvol; in this respect it is more like a disklabel
   partition or wedge than a disk drive.
