  SVN rev 221967 on 2011-05-15 16:16:48Z by ae
  
  Some partitioning schemes want to have partitions that are aligned
  with geometry. And they do recalculation of user specified parameters.
  MBR, PC98, VTOC8, EBR schemes are doing that. For these schemes an
  auto alignment feature (ie. gpart add -a alignment) would not work.
  But it can work for GPT and BSD schemes. BSD scheme usualy is created
  inside MBR, so we can use knowledge about offset of MBR partition to
  calculate aligned values for BSD partitions.
  
  Use "offset" attribute of the parent provider for better alignment.
