+# raspberry pi setup using Arch linux ARM
+
+![logo](https://i.imgur.com/N0Y4vco.png)
+
+Tested on RPi3
+
+# Get Arch on it 
+
+* **download** pre-prepared **image**, aarch64, if not terribly out of date<br>
+  [https://github.com/andrewboring/alarm-images/releases](https://github.com/andrewboring/alarm-images/releases)
+* **flash** the image to to an sd card using [etcher](https://etcher.balena.io/#download-etcher) 
+* **boot** the rpi with it, login root//root
+
+Or follow [the official instructions.](https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3)
+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`<br>
+  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`<br>
+  if it refuses - `pacman-key --init`; `pacman-key --populate`<br>
+  Can take some time.
+* update the system `pacman -Syu` 
+* create a new user and set the password
+  * `useradd -m -G wheel bastard`<br>
+  * `passwd bastard`
+  * edit sudoers to allow users of the group wheel to sudo<br>
+    `EDITOR=nano visudo`<br>
+    `%wheel ALL=(ALL) ALL`
+* install sudo `pacman -S sudo` 
+* try login as the new user
+
+# Run prepared ansible
+
+[This ansibe playbooks repo](https://github.com/DoTheEvo/ansible-arch)
+setup some stuff for arch.<br>
+But for arm based stuff it needs some adjustment.
+
+#### Locale
+
+Ansible needs utf8 [locale](https://wiki.archlinux.org/title/locale) set.
+
+  * run `locale`, if its already UTF-8 then we are done here
+  * `sudo nano /etc/locale.gen`<br>
+    `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.
