That is the great (and best practices) advice,  but I think he actually 
wanted to keep using Partitions/Slices also out of GPT disk(s), too.

Of course it is always better to use full-disk(s) for pools, because of 
illumos using disk cache better with fuill-disk, but it is possible to 
install and use also GPT partitions and make full-partition slice under 
it. (give empty space to installer to make GPT partition and Slice in it)
