- The contents of images generated by the OpenEmbedded build system can be controlled by the
- <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_FEATURES" title="IMAGE_FEATURES">IMAGE_FEATURES</a></code>
- and <code class="filename"><a class="link" href="ref-variables-glos.html#var-EXTRA_IMAGE_FEATURES" title="EXTRA_IMAGE_FEATURES">EXTRA_IMAGE_FEATURES</a></code>
- variables that you typically configure in your image recipes.
- Through these variables you can add several different
- predefined packages such as development utilities or packages with debug
- information needed to investigate application problems or profile applications.
- </p>
- <p>
- Current list of
- <code class="filename">IMAGE_FEATURES</code> contains the following:
- </p>
- <div class="itemizedlist"><ul class="itemizedlist" type="disc">
- <li class="listitem"><p><span class="emphasis"><em>splash:</em></span> Enables showing a splash screen during boot.
- By default, this screen is provided by <code class="filename">psplash</code>, which does
- allow customization.
- If you prefer to use an alternative splash screen package, you can do so by
- setting the <code class="filename">SPLASH</code> variable
- to a different package name (or names) within the image recipe or at the distro
- configuration level.</p></li>
