Install Arch Linux

Install Arch Linux is thing I always want to do for my laptop/PC since I had my laptop in ninth grade.

This is not a guide for everyone, this is just save for myself in a future and for anyone who want to walk in my shoes.

Installation guide

Pre-installation

Check disks carefully:

lsblk

USB flash installation medium

Verify the boot mode

Check UEFI mode:

ls /sys/firmware/efi/efivars

Connect to the internet

Use iwd.

Update the system clock

timedatectl set-ntp true

Partition the disks

GPT fdisk:

cgdisk /dev/sdx

Partition scheme

UEFI/GPT layout:

Mount point Partition Partition type Suggested size
/mnt/efi /dev/efi_system_partition EFI System Partition 512 MiB
/mnt/boot /dev/boot_system_partition Extended Boot Loader Partition 1 GiB
/mnt /dev/root_partition Root Partition
/mnt/var /dev/var_partition Var Partition >= 12 GiB
/mnt/home /dev/home_partition Home Partition
/dev/swap_partition Swap

BIOS/GPT layout:

Mount point Partition Partition type Suggested size
BIOS boot partition 1 MiB
/mnt /dev/root_partition Root Partition
/mnt/var /dev/var_partition Var Partition >= 12 GiB
/mnt/home /dev/home_partition Home Partition
/dev/swap_partition Swap

Format:

# efi
mkfs.fat -F32 /dev/efi_system_partition

# boot
mkfs.fat -F32 /dev/boot_system_partition

# root
mkfs.ext4 -L ROOT /dev/root_partition
mkfs.btrfs -L ROOT /dev/root_partition

# var
mkfs.ext4 -L VAR /dev/var_partition
mkfs.btrfs -L VAR /dev/var_partition

# home
mkfs.ext4 -L HOME /dev/home_partition
mkfs.btrfs -L HOME /dev/home_partition

# swap
mkswap /dev/swap_partition

Mount:

# root
mount /dev/root_partition /mnt
# btrfs
mount -o compress=zstd /dev/root_partition /mnt

# efi
mkdir /mnt/efi
mount /dev/efi_system_partition /mnt/efi

# boot
mkdir /mnt/boot
mount /dev/boot_system_partition /mnt/boot

# var
mkdir /mnt/var
mount /dev/var_partition /mnt/var
# btrfs
mount -o compress=zstd /dev/var_partition /mnt/var

# home
mkdir /mnt/home
mount /dev/home_partition /mnt/home
# btrfs
mount -o compress=zstd /dev/home_partition /mnt/home

# swap
swapon /dev/swap_partition

hwclock --systohc

Localization:

Edit /etc/locale.gen:

# Uncomment en_US.UTF-8 UTF-8

Generate locales:

locale-gen

Edit /etc/locale.conf:

General recommendations

Always remember to check dependencies when install packages.

System administration

Users and groups

Add user:

useradd -m -G wheel -s /bin/bash -c "The Joker" joker

Set password:

passwd username
