Arch Linux ARM on Crostini

I got Arch Linux ARM installed on a Lenovo Chromebook Duet! I mostly used the instructions from the Arch Wiki as reference.

0. Before we begin

TL;DR
Zsh initializations
- Zsh way of $PATH
- the special macOS
/usr/libexec/path_helper

The .*shrc file

Installing Arch Linux ARM on a SD card for Raspberry Pi 0 W and loading wifi credentials for headless usage

Advice

Before starting I highly suggest you create a new directory on your /home/user directory with an appropiate name for this task like rpi0alarm so you can change directory to /home/user/rpi0alarm and go through the following steps.

As I wrote this guide after collecting info from different sources (listed at the end) be mindful of your current path and the commands you are running to not damage your current installation on the host computer you are creating the SD Card.

如何给开源项目贡献代码

分两种情况：

代码仓库管理者给你添加该仓库的写入权限，这样的话可以直接push
如果不能直接push（大多数情况），采用经典的fork & pull request来提交代码，下面讲述这种情况

fork & pull request

例如有个仓库https://github.com/ecomfe/esui.git，其采用了经典的分支开发模型，稳定后的代码提交到master分支，其余特性则在dev分支上进行开发，待成熟后合并回master分支。

	How to boot Arch Linux ARM in QEMU (patched for M1)

	Prerequisites:

	QEMU - patched for M1 processors - patches: https://github.com/utmapp/qemu

	$.fn.select2.amd.define('select2/data/extended-ajax',['./ajax','../utils','jquery'], function(AjaxAdapter, Utils, $){

	function ExtendedAjaxAdapter ($element,options) {
	//we need explicitly process minimumInputLength value
	//to decide should we use AjaxAdapter or return defaultResults,
	//so it is impossible to use MinimumLength decorator here
	this.minimumInputLength = options.get('minimumInputLength');
	this.defaultResults = options.get('defaultResults');

	ExtendedAjaxAdapter.__super__.constructor.call(this,$element,options);

	; This code is hereby released by its author (Per Vognsen) into the public domain.
	; It's mostly a proof of concept though it was surprisingly usable for how simple it was to code.
	; If you want to use it as a starting point for a more polished package, go right ahead.
