Krapaince's archiso sources

My custom Arch ISO. The purpose of this custom ISO is to ease Arch install process by applying my settings and config.

Requirements

An arch machine with the archiso package.

Build

Just run the make-iso.sh script at the repo root.

How it works

The archlive folder is a copy of the relang config from the archiso package. Plus, it contains my custom installer. The installer is a python script (airootfs/etc/usr/local/bin) that does the following:

• Check that boot mode is EFI
• Check for an internet connection
• Update system clock
• Ask the user if they want a separate partition for home
• Ask the user if they want parition(s) to be encrypted
• Ask on which disk to install the system
• Ask for partition(s) size (can be left empty to take the whole disk)
• Create a GPT table, a boot, root (and a home) paritions on the selected disk
• Mount paritions
• Generate fstab
• Install via pacstrap the following packages: archlinux-keyring, base, base-devel, git, {cpu_manufacturer}-ucode, linux, linux-firmware, man-db, man-pages, neovim, networkmanager, python3

Once done the install script copies and runs the configuration script.

The configuration script is executed in chroot on the newly installed system. It does the following:

• Set the timezone
• Set the locale
• Set the hostname and /etc/hosts
• Generate initramfs
• Update pacman's keyring
• Setup sudo (add wheel group to sudoers)
• Set root password
• Configure boot loader (bootctl)
• Create skeleton structure directory for user
• Create user which is a member of the group wheel and set its password

Steps run as the newly created user:

• Install paru
• Steps run if krapaince_config.install is true:
  • Install dotdrop
  • Install Krapaince's config

The configuration script comes with a config file (airootfs/etc/usr/local/share/installer/config.json). The config file can be edited prior to building the ISO or directly on the live OS. However the config can't be saved on the live ISO across reboot.

Config

The config is a json file which contains the following fields:

• hostname (str): hostname of the machine
• lang (str): value used in /etc/locale.conf (Default: en_US.UTF-8)
• locale_gen (Array of string): each value is written to /etc/locale.gen (Default: ["en_US.UTF-8 UTF-8", "en_US ISO-8859-1"])
• timezone (str): timezone (Default: Europe/Paris)
• username (str): name of the user you which to create
• skel (Array of string): list of folders to create in /etc/skel
• krapaince_config (Krapaince config object):
  • install (boolean): whether or not to install my dotfiles
  • dotdrop_profile (str): which dotdrop profile to install (See available values here)

Roadmap

• Improve intaller.py to install on a disk with an existing partition

Known issues

• Sometimes package installation will fail due to keyring errors even if the archlinux-keyring package is install. To pass through this error, just reboot.
