 }  The installer aligns partitions (depending on disk total size and sector
 }  size, in your case apparently to 2048 block boundaries). The second gap
 }  in your setup is a side effect of that and could be avoided though.
 }  
 }  You should be able to work around it by switching from "MB" or "GB" as
 }  input size to single blocks (which is considered an expert option and
 }  not recommended for normal installs).
 
      See this to get automatic alignment of both start and size:
 
      gpt add [-a alignment] [-b blocknr] [-i index] [-l label] [-s size] [-t
              type]
              The add command allows the user to add a new partition to an
              existing table.  By default, it will create a UFS partition
              covering the first available block of an unused disk space.  The
              command-specific options can be used to control this behaviour.
 
              The -a alignment option allows the user to specify an alignment
              for the start and size.  The alignment is given in bytes and may
              have a suffix to indicate its magnitude.  gpt will attempt to
              align the partition.
