## Format disks (repeat for all devices as desired)
# fdisk -l # identify devices
# lsblk -f # identify partitions
# smartctl -i /dev/sda # get serial number and other info

# — Create /boot partition —
# [New]
# [enter] to set default sector size (2048)
# +512M [enter] to set a 512MiB partition size
# ef00 [enter] to set partition type as EFI System Partition
# ESP [enter] to name this partition «ESP»
# — Create swap partition (optional unless low memory) —
# Select free space at end
# [New]
# -4G [enter] to set start sector
# [enter] to set size as remaining end space
# 8200 [enter] to set partition type as Linux swap
# Swap [enter] to name this partition «Swap»
# — Create / partition —
# Select free space at end (or middle, if you created swap)
# [New]
# [enter] to set start sector at beginning of free space
# [enter] to set end sector at end of free space
# [enter] to set partition type as Linux filesystem (default / 8300)

## Mount partitions
mount /dev/sda2 /mnt # mount the root partition
mkdir /mnt/boot # create /boot folder
mount /dev/sda1 /mnt/boot # mount ESP inside /boot on root partition
## Update mirrorlist
pacman -Sy # sync package manager database
pacman -S reflector # install Reflector
reflector —country ‘US’ # get mirrors in US
-p http # using http protocol
—sort rate # and sort them by speed
—save /etc/pacman.d/mirrorlist # save optimal mirrorlist
## Install system
pacstrap /mnt base base-devel # bootstrap minimal system with base packages
#……………………………………# this will take a while…
#……………………………………# better go find something to do
#……………………………………# for ten minutes or so.
genfstab -U /mnt >> /mnt/etc/fstab # generate filesystem table using UUIDs
arch-chroot /mnt # start running commands inside new system
passwd # set root password
## Timezones
ln -sf /usr/share/zoneinfo/America/Chicago # symbolic link from Central Time
/etc/localtime # to the local timezone
hwclock —systohc # sync system clock with hardware clock
## Locales
echo «en_US.UTF-8 UTF-8» > /etc/locale.gen # overwrite locale generation
echo «ar_JO.UTF-8 UTF-8» >> /etc/locale.gen # append locale generation
locale-gen # generate locales from locale.gen
echo «LANG=en_US.UTF-8» > /etc/locale.conf # set specific locale
## Hostnames
echo «arch» > /etc/hostname # set hostname
echo «127.0.0.1 localhost» > /etc/hosts # loopback localhost ipv4
echo «::1 localhost» >> /etc/hosts # loopback localhost ipv6
echo «127.0.1.1 arch.localdomain arch» >> /etc/hosts # loopback hostname ipv4
