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

Writing an apt proxy conf file /etc/apt/apt.conf.d/proxy.conf as below.

Acquire::http::Proxy "socks5h://127.0.0.1:1080";
Acquire::https::Proxy "socks5h://127.0.0.1:1080";
Acquire::socks::Proxy "socks5h://127.0.0.1:1080";

And the proxy settings will be applied the next time we run apt.

Summary

Vivaldi Technologies currently only provide .deb and .rpm packages but it is possible to install it on different distros. This install script automates the process.

Install and Upgrade

You can use the script to fetch and install the latest public snapshot like so:

chmod +x install-vivaldi.sh # Only needed the first time

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }

	#!/bin/bash
	sudo stty -F /dev/ttyACM0 1200
	echo waiting
	while [ ! -d /media/pi/RPI-RP2 ]; do sleep 0.1; done
	sleep 0.5
	if [ "$*" = "" ]; then echo rebooting; sudo picotool reboot; exit; fi
	echo copying
	cp $1 /media/pi/RPI-RP2
	echo done

	#!/usr/bin/python3
	"""
	Usage:
