SYNOPSIS
     $ gem install sysuuid
     irb> require 'sysuuid'
     irb> sysuuid  #=> "4b7067bd-928b-4656-9960-8a58edc6ff02"
     irb> sysuuid  #=> "3cb722b9-7776-4198-bdd2-dcd228716658"

DESCRIPTION
     Uses uuid_generate from e2fsprogs, which comes standard
     with OS X and Linux.

     It's over 2000 times faster than shelling out to uuidgen.
