Title:
  baremetal deploy helper wastes nova-compute host pagecache

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The baremetal deploy helper dd's images to the target machine. This is
  done without oflag=direct, which means that for a 1GB image, we use up
  ~1GB of local pagecache. This is wasteful, as we won't read any
  substantial amount of the image back.
