A live CD or live DVD is a complete bootable Linux operating system loaded from a CD or DVD. Although there are a lots of live Linux CDs, for seemingly every taste and purpose, it might still be useful on occasion to build your own. This guide details the steps to build a bootable live CD/DVD based on Debian “wheezy”.

Step 1 – Installing the necessary software

These are the software packages you need to install on your Debian system:

apt-get install xorriso live-build syslinux squashfs-tools

Step 2 – Create a basic filesystem

This is a nifty little device for under £100 suitable for a home router.

I am using one running OpenBSD 6.8 for my AAISP PPPoE connection (avoiding the supplied VMG1312-B10A which has a number of issues).

Installation

I bought a SanDisk 16GB USB stick as there were reports the supplied USB stick isn't particularly reliable, plus it's nice to keep it separate in case of backup or selling the device in the future.

Download the OpenBSD miniroot68.img file system and dd(1) it, for example on macOS (assuming /dev/disk2):

(UPDATE (22/3/2019): Added some corrections provided by the original author.)

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.
