(Almost) unattended installation script for Arch Linux

• This script installs Arch Linux on a new machine with minimal user interaction.
• It uses UKIs, i.e. Unified Kernel Images, to boot the system.
• If the TPM is in setup mode, the script will sign the UKI with the TPM.

User interaction is required for

• username
• scecifying the disk the system will be installed on
• Setting the LUKS encryption password

Presets

• Hostname. It is set to "archlinux"
• Start password is set to "password"
  • Can be changed on first login with the command 'passwd'.
• For security reasons, the root account is disabled.
• Timezone is set to "Europe/Berlin"
• Locale is set to "en_US.UTF-8" and "de_DE.UTF-8".
• Keyboard layout is set to "de-latin1-nodeadkeys"
• Disk is partitioned with a 512MB EFI partition and the rest is used for the root partition.
• The root partition is formatted with btrfs.
  • Compression can later be enabled in /etc/fstab, e. g. by adding compress=zstd:1 (for best read performance) or compress=zstd:3 (for more focus on compression ratio) to the options.

Cerdits

• The script is based on Walian's Tech/Linux Blog.
