<h2 id="step1">1.1.1. Download iso</h2>
<p>Visit crux
<a href="http://crux.nu/Main/Download">download page</a> for
more notes before downloading iso. Script
<a href="scripts/setup-iso.sh">setup-iso.sh</a> downloads
iso from master repo and checks md5sum.</p>
<pre>
$ curl -k -O https://serverop.de/crux/crux-3.3/iso/crux-3.3.iso
$ curl -k -O https://serverop.de/crux/crux-3.3/iso/crux-3.3.md5

<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;
bios grub, EFI, boot, root, var, usr, swap and home.
For more information about gpt partitions table read
<a href="http://devil-detail.blogspot.com/2013/07/install-grub2-on-gpt-disk-dedicated-partition.html">devil-detail grub2 on gpt</a>.
Script <a href="scripts/setup-target.sh">setup-target.sh</a>
creates follow partitions;</p>
<p>Create gpt label and set unit size to use;</p>
<pre>
(parted) mklabel gpt
(parted) unit mib
</pre>
<h3>bootloader</h3>
<p>Partition used by grub boot loader. Partition size 2M;</p>
<pre>
mkpart primary 2 4
name 1 grub
set 1 bios_grub on
</pre>
<h3>/boot/efi</h3>
<p>EFI System Partition, ESP type EF00. Partition
with between 500M and 100M is recommended for standard
installations. Partition size 128M;</p>
<pre>
(parted) mkpart ESP fat32 4 125
(parted) name 2 efi
(parted) set 2 boot on
</pre>
<h3>/boot</h3>
<p>Boot partition. Partition with 1G provide room for kernels
and crux iso that can be directly boot from grub (without root
partition). Partition size 1G;</p>
<pre>
(parted) mkpart primary ext4 125 1128
(parted) name 3 boot
</pre>
<h3>/</h3>
<p>Normal core crux installation root partition uses
approximately 2G, without /usr 200MB-500M. Minimum 2G
is recommended to give room to root home directory with
dedicated (separated) usr and var partition.
Partition size 4G;</p>
<pre>
(parted) mkpart primary ext4 1128 5128
(parted) name 4 root
</pre>
<h3>/var</h3>
<p>Var partition is recommended 1G-5G depending on how
system is configured. Partition size 1G;</p>
<pre>
(parted) mkpart primary ext4 5128 6128
(parted) name 5 var
</pre>
<h3>/usr</h3>
<p>User partition with 4G-8G is recommended for a desktop
setup, with dedicated partition for ports. Partition size
8G;</p>
<pre>
(parted) mkpart primary ext4 6128 14128
(parted) name 6 usr
</pre>
<h3>Swap (ram)</h3>
<p>Swap partition general advice is to have the same size as
memory ram, ports system will be configured to build on ram.
To build firefox is necessary at least 34G, swap partitions
will be added to lvm and this partition removed.
Partition size 4G;</p>
<pre>
(parted) mkpart primary linux-swap 14128 18128
(parted) name 3 swap
</pre>
<h3>/home</h3>
<p>Home partition general advice is to fill the rest of disk
space. Home partition will be added later to lvm and this
partition removed. Fill the rest of disk space;</p>
<pre>
(parted) mkpart primary ext4 18128 100%
(parted) name 8 home
</pre>
