+## 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. `systemctl enable NetworkManager --now`
+27. Enable and sync time: `systemctl enable systemd-timesyncd --now`
+28. Get tz from `tzselect`, set via `timedatectl set-timezone [tz]`
+29. Update hwclock: `hwclock -w --utc`
