Under heavy rework! PLS do not use ATM!

An opinionated, optimistic installer for the Archlinux operating system.

Never use scripts you found on the internet blindly!

The purpose of this script is to make Archlinux installation a breeze in my preferred way. It consist of two scripts, the disks.bash and installer.bash.

This script is not designed for dual-boot!

The disks.bash script is for formatting the partitions to be used for the installation. It is expected to be run on already created, but empty partitions. It will do the following:

• Prompt for the partition to be used as EFI and root (/).

• Prompt if you would like to encrypt the root partition.

• Formats the EFI partition to FAT32.

• Formats the root partition (with LUKS if enccryption was chosen).

• Sets up btrfs subvolumes for the root partition

  • @ (/)
  • @home (/home)
  • @var (/var)

• Mounts everything under /mnt

    / (@)
    -> /boot/efi (EFI)
    -> /home (@home)
    -> /var (@var)
  

The installer.bash script will create the Archlinux installation. It assumes the necessary partitions are mounted under /mnt, and the EFI partition is mounted under /boot/efi. The steps are the following:

• Install the jq package for the live environment.
• Detect the root and EFI partitions.
• Prompt the user for install options.
  • Prompt which kernels the user would like to install (kernels from the Archlinux repositories).
  • Prompt for username and password.
  • Prompt for hostname.
  • Prompt additinal features.
    • snapper Set up snapper for automatic backups on system upgrades.
    • recovery Copies the booted Archlinux live iso into the EFI partition, and creates an entry for it in systemd-boot.
    • iwd For connecting to WI-FI networks from the terminal.
    • linger Set up user lingering.
    • bluetooth Set up bluetooth support and cli.
• Does all the prompted steps, and additionally it will:
  • Set up locale according to the following:
    • en_US.UTF-8 for locale.gen.
    • us-acentos for KEYMAP.
    • en_US.UTF-8 for LANG, LANGUAGE, LC_ALL.
    • Sets timezone to UTC.
  • Configures networking (systemd-resolved and systemd-networkd, ufw)
    • DNSSEC, DNSOverTLS, Cloudflare DNS.
    • DHCP for any network other than virtual ethernet.
    • ufw firewall (deny incoming, allow outgoing and routed).
  • Configures systemd-boot
  • Configures mkinitcpio with UKIs (Unified Kernel Image).
  • Enables services:
    • systemd-boot-update
    • systemd-timesyncd
    • systemd-oomd
    • systemd-resolved
    • systemd-networkd

After the script finished, the installed system represents my ideal default configuration, but it is most likely not 100% what you want. Do some adjusting by hand, for the repository, or use Ansible to do any additional steps you require.
