Compile an ISO image of the operating system step by step

Link: Build Manjaro ISOs with buildiso

The task is to build prototype distr based on Manjaro Linux.

Install Manjaro Tools

pamac install manjaro-tools-iso

Copy manjaro-tools settings to your home .config:

cp -R /etc/manjaro-tools  ~/.config

Download the latest ISO profiles anywhere in your home catalog:

git clone https://gitlab.manjaro.org/profiles-and-settings/iso-profiles.git ~/.environment/application/iso-profiles

Specify your path to the directory with Manjaro profiles:

touch ~/.config/manjaro-tools/iso-profiles.conf
echo 'run_dir=/home/operator/.environment/application/iso-profiles' >> ~/.config/manjaro-tools/iso-profiles.conf

Check if everything is ok. Print some info about it:

buildiso -q

buildiso -qv

buildiso -qf

Build command:

buildiso -p xfce

If you did not change the paths in manjaro-tools.conf the resulting xfce ISO is stored at /var/cache/manjaro-tools/iso/community/xfce

Preparations for creating an ISO image are now complete. Go to iso-profile:

cd ~/.environment/application/iso-profiles

Let's continue building the environment with XFCE. This is a test project, let's remove the unnecessary from the catalog so as not to distract.

rm -rf .gitignore README.md oem community
cd manjaro && rm -rf !(*xfce) && cd ..

The next step is to create a skel directory with personal data and configuration files. All files and folders in the skel directory will be copied to the user's home catalog.

mkdir manjaro/xfce/desktop-overlay/etc/skel

After creating the skel dir, copy all the necessary settings files into it:

cp -r ../../workspace/skel/global manjaro/xfce/desktop-overlay/etc/skel
cp -r ../../workspace/skel/glocal/unix manjaro/xfce/desktop-overlay/etc/skel

echo '
# User settings
autologin="true"
multilib="true"
extra="true"
hostname="unix"
username="operator"
' >> ~/.environment/application/iso-profiles/manjaro/xfce/profile.conf

echo '
# User settings
target_branch=stable
kernel="linux61"
chroots_dir=/home/operator/Downloads/
' >> ~/.config/manjaro-tools/manjaro-tools.conf

Define what software is needed and edit Packages-Desktop. Editing already present packages is risky:

  • extra packages will be installed in the full build, others in a minimal build
  • -f use if you want to compile full image
  • -b specify a branch, for example stable
  • -k specify the version of the Linux kernel
  • -t specify where to save iso

Building the Manjaro ISO image can be run with the buildiso -p command, specifying the working environment, in our case xfce:

Minimal build:

buildiso -p xfce -k linux61 -b stable

Full build:

buildiso -f -p xfce -k linux61 -b stable -t /home/operator/Downloads

The build process will take some time. It depends on the computer configuration and internet speed.

When rebuilding, but with different parameters, it will be need to remove some files from the previous build:

sudo rm -r /var/lib/manjaro-tools/buildiso/
sudo rm -r /var/cache/manjaro-tools/

sudo rm -r ~/.config/manjaro-tools

Inject AUR packets into build

Link: Buildiso with AUR packages

# Create directory for online repo
mkdir pkg && cd pkg && mkdir -p aur-repo/x86_64

# Create a catalog to build the packets 
mkdir pkgbuild && cd pkgbuild

# Clone packet from AUR 
git clone https://aur.archlinux.org/vscodium-bin.git

# Set prerequisites
sudo pacman -S manjaro-tools-pkg-git

# Building with buildpkg
buildpkg -p vscodium-bin

# Copy packet to repo catalog
cd .. && cd aur-repo
sudo mv /var/cache/manjaro-tools/pkg/stable/x86_64 .

# Generate package database
cd x86_64
repo-add aur-repo.db.tar.gz *.pkg.tar.*

Upload the AUR repo to GitHub, for example:

https://tursky.github.io/aur-repo/x86_64/

Implement an online repository with recompiled packages:

user-repos.conf at iso-profiles/manjaro/xfce:

[aur-repo]
SigLevel = Never
Server = https://tursky.github.io/$repo/$arch

Add packet to Packages-Desktop:

echo '
## AUR packets
vscodium-bin' >> ~/.environment/application/iso-profiles/manjaro/xfce/Packages-Desktop

Cleaning build environment:

 sudo rm -r /var/lib/manjaro-tools/buildpkg

If to rename the xfce directory to prototype, for example, then this must be specified during compilation:

buildiso -f -p prototype -k linux61 -b stable -t /home/operator/Downloads

Or change default settings in manjaro-tools:

cd ~/.config/manjaro-tools/iso.list.d && ls -a

To create a bootable USB flash drive, there are built-in tools:

Find where the flash driver is mounted:

sudo fdisk -l

/sdc or /sdb is the target flash drive:

sudo dd bs=4M if=/home/operator/Downloads/manjaro/xfce/22.1.0/manjaro-prototype-22.1.0-230501-linux61.iso of=/dev/sdb status=progress oflag=sync
