<h1>1.1. Install Crux 3.2</h1>
<p>Installation of minimal Crux 3.2 Gnu\Linux system,
with selected packages from core, opt and contrib
ports. Process of installation documented can be
executed from iso or from existing gnu\linux installation.

<h2 id="step2">1.1.2. Prepare Target</h2>
<p>Prepare disk or target location where new system will
be installed. Follow steps describe how to create efi and
separate partitions such as; boot, root, var, tmp,
usr, ports, swap and home.</p>
<h3>/boot/efi</h3>
<p>EFI System Partition, ESP type EF00. Partition
with between 500M and 100M is recommended for standard
installations.</p>
<pre>
(parted) mkpart ESP fat32 1MiB 120MiB
</pre>
<pre>
(parted) align-check opt 1
</pre>
<h3>/boot</h3>
<p>Boot partition. Partition with 1G provides
room for crux iso to boot directly from grub.</p>
<pre>(parted) mkpart primary ext4 120MiB 1000MiB</pre>
<pre>
(parted) align-check optimal 2
</pre>
<h3>/</h3>
<p>Normal installation root partition uses 200MB-500MB, being
1G recommended. Since we have plenty of space a partition
with 2G will be used to host a complete backup of final installation
configuration.</p>
<pre>
(parted) mkpart primary ext4 1000MiB 3000MiB
</pre>
<pre>
(parted) align-check optimal 3
</pre>
<h3>/var</h3>
<p>Var partition is recommended 100MiB-500MiB, we will
use 1G;</dd>
<pre>
(parted) mkpart primary ext4 3000MiB 4000MiB
</pre>
<pre>
(parted) align-check optimal 4
</pre>
<h3>/tmp</h3>
<p>Temp partition with 20M-50M;</dd>
<pre>
(parted) mkpart primary ext4 4000MiB 4050MiB
</pre>
<pre>
(parted) align-check optimal 5
</pre>
<h3>/usr</h3>
<p>User partition with 4G is recommended for a desktop
setup, we will use 8G;</dd>
<pre>
(parted) mkpart primary ext4 4050MiB 12000MiB
</pre>
<pre>
(parted) align-check optimal 6
</pre>
<h3>/home</h3>
<p>Home partition with 180G;</dd>
<pre>
(parted) mkpart primary ext4 12000MiB 192000MiB
</pre>
<pre>
(parted) align-check optimal 7
</pre>
<h3>/usr/ports</h3>
<p>Ports partition with 120G allows to host sources, package
backups and ports;</dd>
<pre>
(parted) mkpart primary ext4 192000MiB 312000MiB
</pre>
<pre>
(parted) align-check optimal 8
</pre>
<h3>Swap (ram)</h3>
<p>Swap partition general advice is same size as memory ram,
ports system configured to build on ram need at least 30G
to build firefox. Other swap partitions can be added later for port
build on ram.</p>

(parted) mkpart primary linux-swap 312000MiB 342000MiB
