|
|
|
<p>I am the Lorax. I speak for the trees [and images].</p>
|
|
|
|
|
<p>Lorax is used to build the Anaconda Installer boot.iso, it consists of a
|
|
|
|
|
library, pylorax, a set of templates, and the lorax script. Its operation
|
|
|
|
|
is driven by a customized set of Mako templates that lists the packages
|
|
|
|
|
to be installed, steps to execute to remove unneeded files, and creation
|
|
|
|
|
of the iso for all of the supported architectures.</p>
|
|
|

<h1>Before Lorax<a class="headerlink" href="#before-lorax" title="Permalink to this headline">¶</a></h1>
|
2019-03-27 23:44:14 +00:00
|
|
|
<p>Tree building tools such as pungi and revisor rely on 'buildinstall' in
|
2015-05-11 23:44:09 +00:00
|
|
|
anaconda/scripts/ to produce the boot images and other such control files
|
|
|
|
|
in the final tree. The existing buildinstall scripts written in a mix of
|
|
|
|
|
bash and Python are unmaintainable. Lorax is an attempt to replace them
|
|
|
|
|
with something more flexible.</p>
|
|
|
|
|
<p>EXISTING WORKFLOW:</p>
|
|
|
|
|
<p>pungi and other tools call scripts/buildinstall, which in turn call other
|
2019-03-27 23:44:14 +00:00
|
|
|
scripts to do the image building and data generation. Here's how it
|
2015-05-11 23:44:09 +00:00
|
|
|
currently looks:</p>
|
|
|
|
|
<blockquote>

<li><p>find anaconda release RPM</p></li>
|
|
|
|
|
<li><p>unpack RPM, pull in those versions of upd-instroot, mk-images,
|
|
|
|
|
maketreeinfo.py, makestamp.py, and buildinstall</p></li>
|

|
|

<p>-> call maketreeinfo.py</p>
|
|

<p>-> call mk-images (which figures out which mk-images.ARCH to call)</p>
|
|
|
|
|
<p>-> call makestamp.py</p>
|

</ul>
|
|

|
|
</dd>
|
|
|
|

|
|
|
|
|
</div></blockquote>
|
|
|
|
|
<p>PROBLEMS:</p>
|
|
|
|
|
<p>The existing workflow presents some problems with maintaining the scripts.
|
|
|
|
|
First, almost all knowledge of what goes in to the stage 1 and stage 2
|
|
|
|
|
images lives in upd-instroot. The mk-images* scripts copy things from the
|
|
|
|
|
root created by upd-instroot in order to build the stage 1 image, though
|
2019-03-27 23:44:14 +00:00
|
|
|
it's not completely clear from reading the scripts.</p>
|
2015-05-11 23:44:09 +00:00
|
|
|
<p>NEW IDEAS:</p>
|
|
|
|
|
<p>Create a new central driver with all information living in Python modules.
|
|
|
|
|
Configuration files will provide the knowledge previously contained in the
|
|
|
|
|
upd-instroot and mk-images* scripts.</p>
