## 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](https://archlinux.org/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:
|
|
|
|
```bash
|
|
cryptsetup luksFormat <disk>p2
|
|
cryptsetup luksOpen <disk>p2 <diskname>p2_crypt
|
|
```
|
|
|
|
5. Create volumes:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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)
|
|
|
|
```bash
|
|
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`):
|
|
|
|
```bash
|
|
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
|
|
|
|
```conf
|
|
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`
|
|
|
|
```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
|
|
|
|
```bash
|
|
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]`
