Installing Arch Linux on ClockworkPi DevTerm A06

Cole Smith

Introduction

This document will walk you through installing Arch Linux ARM on the DevTerm A06. At the time of writing, only Armbian is supported on the DevTerm.

Steps

Install qemu-user-static (yay -S qemu-user-static).
- This might need you to install pcre-static and update PGP keys (follow the tips in the comments here).
If not already present, install systemd-binfmt, the revamped version of binfmt-support tools
- Your system has to support transparent Qemu user emulation, but fortunately, that is mostly enabled once the steps here have been followed.
Check the status of the systemd-binfmt unit (systemctl status systemd-binfmt) and (re)start if needed (sudo systemctl restart systemd-binfmt)
- This unit has ARM support by default, but check the current documentation to make install it if needed
Mount the root partition of the ARM system into a folder (for e.g., sudo mount /dev/sdb2 arm_mountpoint)
Copy the QEMU ARM static binary (/usr/bin/qemu-arm-static on my distro) to the mounted root directory's usr/bin

NOTICE: This will take up about 3 GB of space on your device, before syncing any repos or projects.

Install Termux from the Play Store and launch it

Once it finishes unpacking:

pkg update

pkg upgrade -y

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

[Unit]
Description=%i service with docker compose
PartOf=docker.service
After=docker.service

Read-only FS on Raspberry Pi

Most embedded devices use a read-only root filesystem. This can make them more resilient to unexpected shutdowns that could otherwise cause data corruption. Depending on your application, you might consider your Pi to be an embedded system. This can also help with some issues that can come from SD card unreliability.

Full instructions and explanations are obtained from this link but you can run these commands directly. I modified some of the instructions for personal convenience.

Login with default username and password: (ArchLinux Arm: alarm, alarm, Raspbian: pi, raspberry)

Optionally enable root over SSH. The rest of these instructions assume you are in root.

nano /etc/ssh/sshd_config

경사스러운 일입니다. 이제 이 곳에 달리는 댓글을 막을 수 있어 그리 하게 되었습니다. 그래도 이전에 달렸던 댓글들은 아무래도 볼 수 있는 다른 방법이 인터넷 상에 존재하긴 하는 모양입니다.
