Introduction

This document describes disk partitioning and installation of the minimal Arch Linux system with LVM-in-LUKS, systemd-boot and network capabilities.

Created at 2022-05-22T23:58:54Z and not so well maintained as I rarely use it.

Create installation medium

1. Download via torrent
2. Verify: sha256sum <path> | grep <checksum>
3. Find usb device name: lsblk
4. Create installation medium: dd if=<path> of=/dev/<device> bs=1MiB

Install

1. Boot to USB image
2. On loader screen press e, append nomodeset the at end of linux commans
3. Partitioning: parted <disk> (see name via lsblk)

mklabel gpt
mkpart ESP fat32 1MiB 513MiB
set 1 boot on
mkpart primary ext4 514MiB 100%
quit

4. Encrypt & open:

cryptsetup luksFormat <disk>p2
cryptsetup luksOpen <disk>p2 <diskname>p2_crypt

5. Create volumes:

pvcreate /dev/mapper/<diskname>p2_crypt
vgcreate main /dev/mapper/<diskname>p2_crypt
lvcreate -L <RAM+2G>G main -n swap
lvcreate -L <N>G main -n root
lvcreate -l 100%FREE main -n home

6. Create FS:

mkfs.ext4 /dev/mapper/main-root
mkfs.ext4 /dev/mapper/main-home
mkswap /dev/mapper/main-swap
mkfs.fat -F32 /dev/<disk>p1

7. Mount:

mount /dev/mapper/main-root /mnt
mkdir /mnt/home /mnt/boot
mount /dev/mapper/main-home /mnt/home
mount /dev/nvme0n1p1 /mnt/boot
swapon /dev/mapper/main-swap

8. Wifi setup (if needed)

iwctl device list
iwctl station [device] connect [network_name]

9. Update keyring (iso may be too old): pacman -Sy archlinux-keyring
10. Install (for wifi you also need networkmanager):

pacstrap -i /mnt base linux linux-firmware intel-ucode lvm2 sudo vim polkit

11. Disks: genfstab -U /mnt >> /mnt/etc/fstab
12. Change root: arch-chroot /mnt
13. Add loader hooks: vim /etc/mkinitcpio.conf, set

HOOKS=(base udev autodetect microcode keyboard keymap modconf block encrypt lvm2 filesystems fsck)`

14. Make initrams: mkinitcpio -p linux
15. Install bootloader: bootctl install --path=/boot
16. Save disk UUID: cryptsetup luksUUID /dev/<disk>p2 > /boot/loader/entries/arch.conf
17. Make boot config: vim /boot/loader/entries/arch.conf

title Arch
linux /vmlinuz-linux
initrd /initramfs-linux.img
options quiet loglevel=3 cryptdevice=UUID=[uuid]:[disk_name]p2_crypt root=/dev/mapper/main-root rw resume=/dev/mapper/main-swap

18. Make generic boot config: vim /boot/loader/loader.conf, set default arch
19. Create sudo group: groupadd -g 1000 sudo
20. Grant privileges: visudo, uncomment or add line %sudo ALL=(ALL:ALL) ALL
21. Add user

groupadd -g 2000 <username>
useradd -m --groups sudo --gid 2000 --uid 2000 <username>
passwd <username>

22. exit, reboot into real system
23. login, sudo su
24. Uncomment locale in /etc/locale.gen, run locale-gen
25. echo "<name>" > /etc/hostname
26. Get tz from tzselect, set via timedatectl set-timezone [tz]
