My Arch Install

This is my personal Linux installation. I'll be using Arch Linux and Wayland for it's display server.

Assuming you've booted the live environment, got the internet working, and did some partitioning, you can continue following this guide. If not, you can do so by reading the Wiki beforehand.

Update the system clock

Use timedatectl to ensure the system clock is accurate:

# timedatectl set-ntp true

Mount the file systems

Use lsblk to list all the disks and its partitions:

# lsblk

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda      8:0    0 223.6G  0 disk 
├─sda1   8:1    0   512M  0 part
├─sda2   8:2    0   7.7G  0 part
└─sda3   8:3    0  92.5G  0 part

Mount the root volume to /mnt. For example /dev/sda3 will be used:

# mount /dev/sda3 /mnt

Mount the boot partition. But before doing so, you have to create the boot directory inside the /mnt first:

# mkdir /mnt/boot

Then you can proceed mounting the boot partition to /mnt/boot. For example /dev/sda1 will be used:

# mount /dev/sda1 /mnt/boot

If you create a swap volume, you can also enable it. For example /dev/sda2 will be used:

# swapon /dev/sda2

Install essential packages

Use the pacstrap script to install the base and base-devel package, Linux kernel and its headers, firmware for common hardware, microcode for our processors, and also a text editor. I'll be using linux-lts kernel, intel-ucode because my processors are Intel, and vim as my editor:

# pacstrap /mnt base base-devel linux-lts linux-lts-headers linux-firmware intel-ucode vim

Generate an fstab file

# genfstab -U >> /mnt/etc/fstab

You can see the generated files using cat:

# cat /mnt/etc/fstab

Change root into the new system

# arch-chroot /mnt

Set the time zone:

Replace Asia and Jakarta with your own location.

# ln -sf /usr/share/zoneinfo/Asia/Jakarta /etc/localtime

Run hwclock to generate /etc/adjtime:

# hwclock --systohc

Localization

Edit /etc/locale.gen and uncomment en_US.UTF-8 UTF-8, then generate the locales by running:

# locale-gen

Set LANG variable:

# echo 'LANG=en_US.UTF-8' > /etc/locale.conf

Network Configuration

Create the hostname file, I'll be using T480 as my hostname:

# echo 'T480' > /etc/hostname

Edit the /etc/hosts file, and add the following:

127.0.0.1    localhost  
::1          localhost  
127.0.1.1    T480.localdomain	  T480

Make sure to replace T480 with your very hostname.

Root password

Set the root password:

# passwd

User and groups

Add a new user, in this case ssa:

# useradd -mG wheel ssa

Set a password for ssa:

# passwd ssa

Add user to sudoers:

Edit the sudoers using visudo:

EDITOR=vim visudo

To allow members of group wheel sudo access, uncomment this line:

%wheel ALL=(ALL:ALL) ALL

Enable multilib

To enable multilib repository, uncomment the [multilib] section in /etc/pacman.conf:

[multilib]
Include = /etc/pacman.d/mirrorlist

Install the bootloader

I'll be using systemd-boot for my bootloader, you can also use this if your system is UEFI.

Installation

Previously we mount /dev/sda1 as the boot volume. To install the bootloader:
```
# bootctl --path=/boot install
```

Adding loaders

Create a new file for example arch.conf, then edit the file using vim:

# vim /boot/loader/entries/arch.conf

Previously we use /dev/sda3 as our root volume, so edit accordingly:

title   Arch Linux  
linux   /vmlinuz-linux-lts
initrd  /intel-ucode.img
initrd  /initramfs-linux-lts.img  
options root=/dev/sda3 rw

Reboot

Before rebooting, make sure to install networkmanager because you will need them for internet connection:

# pacman -Syu networkmanager

Also enable NetworkManager.service:

# systemctl enable NetworkManager

Then you can safely reboot to your freshly installed Arch Linux, after exiting the chroot of course.
