# Switch into the root with a new system:

Once last part while we was inside archiso was successfully done, it's time to start managing installed system.


You can use archiso later as a recovery tool!

Chroot into the system

arch-chroot /mnt

# Locale

Uncomment needed locales e.g. en_US.UTF-8 UTF-8:

vim /etc/locale.gen

And generate them:


Also add LANG variable:

cat > /etc/locale.conf
echo "LANG=en_US.UTF-8" > /etc/locale.conf

This example will show you how to make dvorak layout persistent:

cat > /etc/vconsole.conf
echo "KEYMAP=dvorak" > /etc/vconsole.conf

If you have AZERTY, colmark etc, just change dvorak with your favorite layout. Do nothing if you have QWERTY.

# Network configuration

Hostname - is a unique name created to identify a machine on a network.

  • Basic method that is working in arch-chroot.: Replace uniquename with anything you want:
echo uniquename > /etc/hostname


The result of this manipulations will be something like: user@uniquename

  • You will be able to generate hostname with hostnamectl later. Be aware that this method is NOT WORKING in arch-chroot.
hostnamectl set-hostname myhostname

Add matching entries to the hosts, edit vim /etc/hosts.     localhost
::1           localhost     uniquename.localdomain uniquename

If the system has a permanent IP address, it should be used instead of
See more in the official docs: network configuration.

# Community repositories

Enabling multilib for the arch community repositories.


multilib is for 64bit system.

To do this open the pacman.conf file:

vim /etc/pacman.conf

Uncomment this:

#Include = /etc/pacman.d/mirrorlist


You also may add unofficial repositories with caution.

  • To have pacman animation add this under the 'Misc options':
  • You will need Color option for yay later.

And update the system. We should let system know about the changes.

pacman -Syyu

# User and password

  • Root password:
  • User password:
    You should add at least one user. Replace username with preferred one:
useradd -m -g users -G wheel,storage,power -s /bin/bash username

And set password for a new user:

passwd username

# Sudoers


Read about visudo before editing! Any errors makes sudo unusable.
Always edit /etc/sudoers file with visudo to prevent errors.

EDITOR=vim visudo

Since you added user to the wheel group, user will gain full root privileges, you need to uncomment this line:

%wheel ALL=(ALL) ALL


If you are using a server or someone else has access to the wheel group, you may want to require sudoers to type root password.
In this case add this line:

Defaults rootpw

Read more about root password.

# Microcode

You should enable microcode updates, my laptop has intel CPU:

pacman -S intel-ucode


Install amd-ucode if you have AMD CPU.
