The files produced for each image are as follows:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p><span class="emphasis"><em>build-id:</em></span>
Human-readable information about the build configuration
and metadata source revisions.</p></li>
<li class="listitem"><p><span class="emphasis"><em>*.dot:</em></span>
Dependency graphs for the image that are
compatible with <code class="filename">graphviz</code>.
</p></li>
<li class="listitem"><p><span class="emphasis"><em>files-in-image.txt:</em></span>
A list of files in the image with permissions,
owner, group, size, and symlink information.
</p></li>
<li class="listitem"><p><span class="emphasis"><em>image-info.txt:</em></span>
A text file containing name-value pairs with information
about the image.
See the following listing example for more information.
</p></li>
<li class="listitem"><p><span class="emphasis"><em>installed-package-names.txt:</em></span>
A list of installed packages by name only.</p></li>
<li class="listitem"><p><span class="emphasis"><em>installed-package-sizes.txt:</em></span>
A list of installed packages ordered by size.
</p></li>
<li class="listitem"><p><span class="emphasis"><em>installed-packages.txt:</em></span>
A list of installed packages with fuill package
filenames.</p></li>
</ul></div>
<p>
</p>
<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
Installed package information is able to be gathered and
produced even if package management is disabled for the final
image.
</div>
<p>
</p>
<p>
Here is an example of <code class="filename">image-info.txt</code>:
</p>
<pre class="literallayout">
DISTRO = poky
DISTRO_VERSION = 1.1+snapshot-20120207
USER_CLASSES = image-mklibs image-prelink
IMAGE_CLASSES = image_types
IMAGE_FEATURES = debug-tweaks x11-base apps-x11-core \
package-management ssh-server-dropbear package-management
IMAGE_LINGUAS = en-us en-gb
IMAGE_INSTALL = task-core-boot task-base-extended
BAD_RECOMMENDATIONS =
ROOTFS_POSTPROCESS_COMMAND = buildhistory_get_image_installed ; rootfs_update_timestamp ;
IMAGE_POSTPROCESS_COMMAND = buildhistory_get_imageinfo ;
IMAGESIZE = 171816
</pre>
<p>
Other than <code class="filename">IMAGESIZE</code>, which is the
total size of the files in the image in Kbytes, the
name-value pairs are variables that may have influenced the
content of the image.
This information is often useful when you are trying to determine
why a change in the package or file listings has occurred.
