<span id="Preparing-Environment-1"></span><h3 class="section">1.1 Preparing Environment</h3>
<p>To install Carbs Linux, you will need a Live Linux ISO. For that purpose, you
can obtain a Gentoo or Void Linux live image. You can follow their instructions
to boot and setup your network.
</p>
<p>You will need the following programs in order to install Carbs Linux:
</p>
<ul>
<li> tar
</li><li> wget
</li><li> xz
</li><li> some form of base utilities (coreutils, sbase, busybox, etc.)
</li></ul>
<p>Rest of these instructions will assume that you have set all of these up, and
will continue on that point.
</p>
<span id="Download"></span><h4 class="subsection">1.1.1 Download</h4>
<p>First, we need to download the rootfs tarball. You can do the following in order
to obtain the rootfs. If you are using an i686 machine, replace the
<code>x86_64</code> with <code>i686</code>. We are setting this in a URL variable so that we
don’t have to write it every time.
</p>
<div class="example">
<pre class="example">$ URL=https://dl.carbslinux.org/releases/x86_64
$ wget $URL/carbs-rootfs.tar.xz
</pre></div>
<p>We can then check the integrity of the tarball and do a signature verification.
Even thought these are optional, they are highly recommended.
</p>
<span id="Check-the-integrity-of-the-tarball-_0028Recommended_0029"></span><h4 class="subsection">1.1.2 Check the integrity of the tarball (Recommended)</h4>
<p>All of the releases are saved in a single file named <samp>sha256sums.txt</samp>, but
the latest release is saved on <samp>carbs-rootfs.tar.xz.sha256</samp>. You can
acquire and verify the tarball.
</p>
<div class="example">
<pre class="example">$ wget $URL/carbs-rootfs.tar.xz.sha256
$ sha256sum -c carbs-rootfs.tar.xz.sha256
</pre></div>
<span id="Verify-the-signature"></span><h4 class="subsection">1.1.3 Verify the signature</h4>
<p>It is highly recommended to verify the signature of the tarball. You will need
GPG for this.
</p>
<div class="example">
<pre class="example">$ wget $URL/carbs-rootfs.tar.xz.sig
$ gpg --recv-keys FF484BDFEFCEF8FF
$ gpg --verify carbs-rootfs.tar.xz.sig
</pre></div>
<span id="Extracting-the-tarball"></span><h4 class="subsection">1.1.4 Extracting the tarball</h4>
<p>You will need to extract the tarball to your desired location. For partitioning,
you can follow <a href="https://wiki.archlinux.org/index.php/Partitioning">this guide</a>.
This will assume that you will be mounting your root partition to <samp>/mnt</samp>.
</p>
<div class="example">
<pre class="example">$ mount /dev/sdx1 /mnt
$ tar xf carbs-rootfs.tar.xz -C /mnt
</pre></div>
<span id="Obtain-the-chroot-helper"></span><h4 class="subsection">1.1.5 Obtain the chroot helper</h4>
<p>You can obtain the <code>cpt-chroot</code> script in order to do a simple chroot into
your new root filesystem.
</p>
<div class="example">
<pre class="example">$ wget https://dl.carbslinux.org/distfiles/cpt-chroot
$ chmod a+x cpt-chroot
</pre></div>
