  16                 As you can see, build history produces image information,
  17                 including dependency graphs, so you can see why something
  18                 was pulled into the image.
  19                 If you are just interested in this information and not
  20                 interested in collecting history or any package information,

  22                 any history by adding the following
  23                 to your <code class="filename">conf/local.conf</code> file found in the
