1. verify the boot mode: `ls /sys/firmware/efi/efivars`
2. verify internet `ping archlinux.org`
3. update system clock `timedatectl set-ntp true`
4. wipe the disk:
    1. `cryptsetup open --type plain -d /dev/urandom /dev/sda to_be_wiped`
    2. `dd if=/dev/zero of=/dev/mapper/to_be_wiped status=progress`
    3. `cryptsetup close to_be_wiped`
5. partition the disk, with cfdisk:
    1. EFI/boot partition 512M (sda1), partition type `EF00` on gdisk
    2. root partition, rest of the space, with LVM format (sda2)
6. create LVM volumes:
    1. list capable devices `lvmdiskscan`
    2. create physical volume `pvcreate /dev/sda2`
    3. create volume groups `vgcreate MyVol /dev/sda2`
    4. create logical volumes `lvcreate -L 8G MyVol -n swap` and `lvcreate -L 100%FREE MyVol -n root`
7. format:
    1. format boot `mkfs.fat -F32 /dev/sda1`
    2. format root `mkfs.ext4 /dev/MyVol/root`
    3. `mkswap /dev/MyVol/swap`
    4. `mount /dev/MyVol/root /mnt` & `swapon /dev/MyVol/swap`
    5. `mkdir /mnt/boot` & `mount /dev/sda1 /mnt/boot`
8. installation: `pacstrap /mnt base`
9. Fstab `genfstab -L /mnt >> /mnt/etc/fstab`
