<h1 id="building-blendos-and-its-packages">Building blendOS (and
its packages)</h1>
<p>This one was pretty simple. First off, I just made <a
href="https://git.askiiart.net/askiiart-blendos">an organization
to hold all my blendOS code</a> on my Forgejo instance just to
keep it organized. Then I just cloned all the relevant
repositories from upstream (<em>blendOS · GitLab</em>), added my
own code with some minor fixes and stuff, then pushed the
updated code to my server.</p>
<p>After that, it was just a matter of adding the actual
packaging for the code. For the packages that were required for
building the blendOS <code>iso</code> file, if I didn't have my
own repository for them already, I just made a new branch,
updated the packaging, and pushed the packaging to that
branch.</p>
<p>Looking at the <a
href="https://git.blendos.co/blendOS/image-builder/-/blob/main/packages.x86_64?ref_type=heads">package
list</a> from <code>image-builder</code> (<em>blendOS /
image-builder · GitLab</em>), it seems the only blendOS-specific
packages it uses are:</p>
<div class="sourceCode" id="cb1"><pre
class="language-txt"><code class="language-default"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>filesystem-blend</span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a>blend-inst-git</span>
<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a>jade-gui</span>
<span id="cb1-4"><a href="#cb1-4" aria-hidden="true" tabindex="-1"></a>blend-git</span>

<span id="cb1-7"><a href="#cb1-7" aria-hidden="true" tabindex="-1"></a>akshara-git</span></code></pre></div>
<p>At first, after a bit of minor troubleshooting, I got this
all set up and working, pretty simple.</p>
<h2 id="oops-it-didnt-work-actually">Oops it didn't work
actually</h2>
<p>I then realized that my <code>iso</code> file worked, but was
not using my repo, and I had even forgotten to even add some of
the packages.</p>
<p>Turns out I had added my repo to the container's
<code>pacman</code> configuration, but not to the
<code>pacman</code> config for <code>archiso</code>, the tool
used to generate the <code>iso</code> file, or the actual
resulting <code>iso</code> image's <code>pacman</code> config
either. So while I would have been able to install anything from
my repo in the container, the repo was unused by
<code>archiso</code>.</p>
<p>I just added the missing packages needed to build the
<code>iso</code> file, plus all the others on blendOS's GitLab,
and rebuilt it. After a bit of troublshooting (nothing
interesting, just incompetency, wrong perms, stuff like that), I
got it working perfectly.</p>
