<p>“I am the Lorax. I speak for the trees [and images].”</p>
|
||
<p>The <a class="reference external" href="https://github.com/rhinstaller/lorax">lorax</a> tool is used to create the
|
||
<a class="reference external" href="https://github.com/rhinstaller/anaconda">Anaconda</a> installer boot.iso as
|
||
well as the basic release tree, and .treeinfo metadata file. Its dependencies
|
||
are fairly light-weight because it needs to be able to run in a mock chroot
|
||
environment. It is best to run lorax from the same release as is being targeted
|
||
because the templates may have release specific logic in them. eg. Use the
|
||
rawhide version to build the boot.iso for rawhide, along with the rawhide
|
||
repositories.</p>

<h2>How it works<a class="headerlink" href="#how-it-works" title="Permalink to this headline">¶</a></h2>
|
||
<p>Lorax uses <a class="reference external" href="https://github.com/rpm-software-management/dnf">dnf</a> to install
|
||
packages into a temporary directory, sets up configuration files, it then
|
||
removes unneeded files to save space, and creates a squashfs filesystem of the
|
||
files. The iso is then built using a generic initramfs and the kernel from the
|
||
selected repositories.</p>
|
||
<p>To drive these processes Lorax uses a custom template system, based on <a class="reference external" href="http://www.makotemplates.org/">Mako
|
||
templates</a> with the addition of custom
|
||
commands (documented in <a class="reference internal" href="pylorax.html#pylorax.ltmpl.LoraxTemplateRunner" title="pylorax.ltmpl.LoraxTemplateRunner"><code class="xref py py-class docutils literal notranslate"><span class="pre">pylorax.ltmpl.LoraxTemplateRunner</span></code></a>). Mako
|
||
supports <code class="docutils literal notranslate"><span class="pre">%if/%endif</span></code> blocks as well as free-form python code inside <code class="docutils literal notranslate"><span class="pre"><%</span>
|
||
<span class="pre">%></span></code> tags and variable substitution with <code class="docutils literal notranslate"><span class="pre">${}</span></code>. The default templates are
|
||
shipped with lorax in <code class="docutils literal notranslate"><span class="pre">/usr/share/lorax/templates.d/99-generic/</span></code> and use the

<code class="docutils literal notranslate"><span class="pre">.tmpl</span></code> extension.</p>
