My latest experiments led me to write https://github.com/lucky-sideburn/generic-distro-toolkit, a project that bundles tons of Ansible, Bash, and Jenkins jobs dedicated to building a GNU/Linux operating system from scratch. Specifically, it’s based on the LFS project, that is https://www.linuxfromscratch.org/lfs/view/stable/.
Of course, LFS is for manually setting up Linux and learning in depth how things work, but my focus is on the DevOps side, using tools like Jenkins and Ansible.
This is an example of a distribution for the x86_64 architecture that I started through virt-install by running the job “0004 – Prepare System Image (System Configuration).”
This post shows the journal of another experiment, where I created an aarch64 system. For this, I started directly on my MacBook Pro M3 using QEMU. The *.img file was passed through the synced folder of the LFS aarch64 build node, which was provisioned with Vagrant.
Project Structure
This is the start of VMs on AARCH64, the first one is an Alpine that I use for debugging, the second one is my (A)LFS
Prequisites
Before starting the operating system build, ensure you have a Jenkins server to coordinate the agent.
For building AMD64 or AARCH64, enable KVM and install libvirt, QEMU, and Cockpit.
For AMD64, I used a physical server with both the Jenkins Master and Agent running on the same node.
For AARCH64 (related to this article), I used my laptop with a VM acting as the Jenkins Agent, connected to a Jenkins Master (you can provision the master wherever you prefer)
Build AARCH64 – GNU/Linux Operating System
Clone https://github.com/lucky-sideburn/generic-distro-toolkit repo
Run start.sh and select “16) Provision an AARCH64 build node using Vagrant”
Run start.sh and create Jenkins folders:
0) Create Jenkins Folders
8) Build AARCH64 all Jenkins Jobs
9) Build AARCH64 cross_toolchain Jenkins Jobs
10) Build AARCH64 cross_compiling_temporary_tools Jenkins Jobs
11) Build AARCH64 chroot_and_building_additional_temporary_tools Jenkins Jobs
12) Build AARCH64 basic_system_software Jenkins Jobs
13) Build AARCH64 system_configuration Jenkins Jobs
14) Build AARCH64 containers Jenkins Jobs
Run Jenkins jobs in the order of the numbered folders and jobs.
Run start.sh and select 15) Start AARCH64 VM on QEMU to work on your GNU/Linux system.
Build AMD64 – GNU/Linux Operating System
Clone https://github.com/lucky-sideburn/generic-distro-toolkit repo
Run start.sh and select “17) Provision an AMD64 build node directly with Ansible”
Run start.sh and create Jenkins folders
0) Create Jenkins Folders
1) Build AMD64 all Jenkins Jobs
2) Build AMD64 cross_toolchain Jenkins Jobs
3) Build AMD64 cross_compiling_temporary_tools Jenkins Jobs
4) Build AMD64 chroot_and_building_additional_temporary_tools Jenkins Jobs
5) Build AMD64 basic_system_software Jenkins Jobs
6) Build AMD64 system_configuration Jenkins Jobs
7) Build AMD64 containers Jenkins Jobs
Run Jenkins jobs in the order of the numbered folders and jobs.
The job 0004 – Prepare System Image (System Configuration) will start the VMs, which can be monitored using Cockpit.
Wishing to build an ARM system, specifically AARCH64, I labeled a Jenkins slave as aarch64
In the definition of the jobs I will create automatically, I will therefore have an assignedNode set with the name of the chosen executor.

- aarch64_jobs
- aarch64_cross_compiling_temporary_toolsJobs are configured for AMD64 and AARCH64 system and are defined in terms for build command in a Ansible Vars file. For example:
- name: 0009 - Grep (Cross Compiling Temporary Tools)
version: 3.11
archive_file: /mnt/lfs/sources/grep-3.11.tar.xz
source_dir: /mnt/lfs/sources/grep-3.11
description: |
Grep is a command-line utility for searching plain-text data for lines that match a regular expression. This job builds Grep, which is essential for text searching in the LFS environment.
category:
This job is part of the cross compiling temporary tools setup, specifically for building Grep.
jenkins_job_url: http://localhost:8080/job/cross_compiling_temporary_tools/job/Grep-3.11%20(Cross%20Compiling%20Temporary%20Tools)/
build_command: |
./configure --prefix=/usr \
--host=$LFS_TGT \
--build=$(./build-aux/config.guess)
make
make DESTDIR=$LFS installPrepare to the chroot…
I would say that the most fundamental tool, and the one I use the most during these activities, is the following.
sudo chroot "$LFS" /usr/bin/env -i \
HOME=/root \
TERM="$TERM" \
PS1='(lfs chroot) \u:\w\$ ' \
PATH=/usr/bin:/usr/sbin \
MAKEFLAGS="-j$(nproc)" \
TESTSUITEFLAGS="-j$(nproc)" \
/bin/bash
I place it with Ansible under Jenkins’ home directory...- name: Copy chroot_lfs.sh to /home/jenkins
ansible.builtin.copy:
src: chroot_lfs.sh
dest: /home/jenkins/chroot_lfs.sh
owner: jenkins
group: jenkins
mode: '0755'
It will be very common to have to enter the chroot environment to see what is not working inside the distro we are building.
Execution version-check.sh
Here https://www.linuxfromscratch.org/lfs/view/stable/chapter02/hostreqs.html a bash script is provided to check the versions of the tools present on the initial system. Running it, I see that everything is fine except for an issue related to Bash itself.

ERROR: sh is NOT Bash
Compiler check:

To fix the error ERROR: sh is NOT Bash, I just need to force sh to point to bash. Do this only in your LFS machines.
ls -l /usr/bin/sh
ln /usr/bin/bash /usr/bin/sh
This should solve problems like the absence of pushd as a built-in in my bash interpreter.
The Server Environment
On the server side, I installed Ansible, Jenkins, Cockpit, and Libvirt.
In Jenkins, I created all the jobs needed to build the projects that are part of the GNU/Linux ecosystem using Ansible. They are defined in the vars of a role that you can find here: https://github.com/lucky-sideburn/Generic-Distro-ToolK1t/blob/main/jenkins-lfs/playbooks/roles/ansible-gdt/vars/main.yml
I am very satisfied with a simple bash script that wraps the playbooks to be called with the relevant tags. I use it for any modifications in the Jenkins folder and jobs or test OS image via QEMU.

Building AARCH64 cross_toolchain Jenkins Jobs...
On Cockpit, I test the newly created VMs from the images built through Jenkins.
On ARM (my MacBook M3), I don’t have Cockpit and KVM, so I will use QEMU.
The AARCH64 (ARM) build node
I’m using my work Apple MacBook Pro M3, on which I provisioned a VM via Vagrant. As you can see, the node is also a slave of my Jenkins, which I manually labeled as aarch64.
# Vagrantfile for Ubuntu ARM
Vagrant.configure("2") do |config|
config.vm.box = "arm64-boxes/ubuntu-22.04"
config.vm.box_version = "0.2"
config.vm.hostname = "ubuntu-arm-lfs"
config.vm.define "ubuntu-arm-lfs"
config.vm.provider "virtualbox" do |vb|
vb.memory = "12288"
vb.cpus = 4
end
config.vm.provision "ansible" do |ansible|
ansible.playbook = "./jenkins-lfs/playbooks/aarch64_lfs.yml"
ansible.become = true
ansible.extra_vars = {
"jenkins_agent_jar" => "/opt/jenkins/agent/agent.jar",
"jenkins_master_url" => "https://jenkins.garantideltalento.it",
"jenkins_user" => "jenkins",
"jenkins_group" => "jenkins",
"jenkins_agent_workdir" => "/opt/jenkins/workdir",
"jenkins_agent_home" => "/opt/jenkins/home",
"jenkins_agent_name" => "ubuntu-arm-lfs",
"jenkins_agent_secret" => ENV['JENKINS_AGENT_SECRET'],
"lfs_repo_url" => "http://repo.garantideltalento.it",
}
end
config.vm.network "private_network", type: "dhcp"
endI created a dedicated Ansible playbook to provision the node. It does very simple tasks and you can find it here: https://github.com/lucky-sideburn/Generic-Distro-ToolK1t/blob/main/jenkins-lfs/playbooks/roles/ansible-gdt/tasks/aarch64_lfs.yml
Basically, the tasks are very simple:

After I prepared the build node and joined it to my Jenkins server as an executor, it is time to create all Jenkins jobs via Ansible, and then run them in the specific order, following the numbered names.

This set of Jenkins jobs automates the complete system configuration and image preparation process. It includes setting up LFS and optional BLFS boot scripts, configuring the core Linux system components, and creating a ready-to-use system image. Together, these jobs ensure a fully configured, functional, and deployable operating system.
Run OS via qemu-system-aarch64
For troubleshooting my operating system (in case of a broken boot, filesystem, or configuration problem), I used the following strategy:
During the image preparation, I create lfs.img as well as lfs-clone.img, which is a clone, as suggested by the name. I run an Alpine Linux live instance to mount the image of the OS that I built.
