raspberry pi setup using Arch linux ARM

Tested on RPi3

Get Arch on it

download pre-prepared image, aarch64, if not terribly out of date
https://github.com/andrewboring/alarm-images/releases
flash the image to to an sd card using etcher
boot the rpi with it, login root//root

Or follow the official instructions. With manual partitioning, and extracting and moving but everything is latest.

Get Arch in to working state

check space used and assigned df -h and lsblk
if root partition is too small
- cfdisk /dev/mmcblk0 or whatever is your drive path, and resize the partition, write changes
- resize2fs /dev/mmcblk0p2 or whatever is the path to the partition
since the image can be older update might not be just pacman -Syu
- update keyring pacman -Sy archlinux-keyring, pacman -Sy archlinuxarm-keyring
  if it refuses - pacman-key --init; pacman-key --populate
  Can take some time.
update the system pacman -Syu
create a new user and set the password
- useradd -m -G wheel bastard
- passwd bastard
- edit sudoers to allow users of the group wheel to sudo
  EDITOR=nano visudo
  %wheel ALL=(ALL) ALL
install sudo pacman -S sudo
try login as the new user

Run prepared ansible

This ansibe playbooks repo setup some stuff for arch.
But for arm based stuff it needs some adjustment.

Locale

Ansible needs utf8 locale set.

run locale, if its already UTF-8 then we are done here
sudo nano /etc/locale.gen
en_US.UTF-8 UTF-8 uncomment
locale-gen - generates locale
localectl set-locale LANG=en_US.UTF-8 - sets locale
logout, login, check locale again

YAY and Reflect

playbook_core.yml installs lot of basic packages. It works for most, except for yay and reflector as they throw an error cuz of ARM archiceture.

So before running playbook_core.yml or after experiencing any error, just edit the playbook_core.yml and delete the responsible section, and run again.

playbook_zsh.yml and playbook_docker.yml worked without any issues.

After its done uninstall ansible stuff - sudo pacman -Rns ansible

The raspberry is now ready.
