<h1>Product and Updates Images<a class="headerlink" href="#product-and-updates-images" title="Permalink to this headline">¶</a></h1>
<p>Lorax now supports creation of product.img and updates.img as part of the build
process. This is implemented using the installimg template command which will
take the contents of a directory and create a compressed archive from it. The
directory must be created by one of the packages installed by
runtime-install.tmpl or by passing <code class="docutils literal notranslate"><span class="pre">--installpkgs</span> <span class="pre">&lt;pkgname&gt;</span></code> to lorax at
runtime.  The x86, ppc, ppc64le and aarch64 templates all look for
/usr/share/lorax/product/ and /usr/share/lorax/updates/ directories in the
install chroot while creating the final install tree. If there are files in
those directories lorax will create images/product.img and/or
images/updates.img</p>
<p>These archives are just like an anaconda updates image – their contents are
copied over the top of the filesystem at boot time so that you can drop in
files to add to or replace anything on the filesystem.</p>
<p>Anaconda has several places that it looks for updates, the one for product.img
is in /run/install/product.  So for example, to add an installclass to Anaconda
you would put your custom class here:</p>
<p><code class="docutils literal notranslate"><span class="pre">/usr/share/lorax/product/run/install/product/pyanaconda/installclasses/custom.py</span></code></p>
<p>If the packages containing the product/updates files are not included as part
of normal dependencies you can add specific packages with the <code class="docutils literal notranslate"><span class="pre">--installpkgs</span></code>
command or the installpkgs paramater of <a class="reference internal" href="pylorax.html#pylorax.treebuilder.RuntimeBuilder" title="pylorax.treebuilder.RuntimeBuilder"><code class="xref py py-class docutils literal notranslate"><span class="pre">pylorax.treebuilder.RuntimeBuilder</span></code></a></p>
