Phyllome OS is a Fedora Remix designed to leverage hardware-assisted virtualization and paravirtualization to make it easier to run virtualized operating systems locally.

Phyllome OS uses the automated kickstart installation method to deploy itself to a specific target computer or virtual machine.

Phyllome OS is in its alpha stage of development. Expect bugs and disappointment

The content of this repository

Each version of Phyllome OS is like a dish that is based on a recipe that lists ingredients, or basic building blocks for assembling Phyllome OS and other derivatives.

ingredients🥑 🥥 🥭 🥝 🥦 🥬 🥒 🧄: Each ingredient represents a feature or a set of integrated features, such as a specific Desktop Environment

cat ingredients/base-storage.cfg

[...]
# What ? This kickstart file provides a basic ext4 unencrypted partition layout for UEFI-based systems

part /boot/efi --fstype="efi" --size=128 --fsoptions="umask=0077,shortname=winnt" --label=efi # Will create an EFI system partitition of 128 MiB (vda1)
part /boot --fstype="ext4" --size=512 --label=boot # Create a boot partition of 512 MiB using the ext4 filesystem (vda2)
part / --fstype="ext4" --grow --label=root # The remaining space will be used for root (vda3)

recipes🧾 🧩: this directory contains recipes for deploying operating system artifacts on bare-metal, as a live system, or inside a virtual machine.

cat recipes/desktop-hypervisor.cfg

# What ? This kickstart file bootstraps a desktop hypervisor.

Development

Let's assume you wish to add Luanti, a free and open-source sandbox video game engine, as an ingredient to a dish.

Clone this repository and change directory:

$ git clone https://git.phyllo.me/roots/phyllomeos && cd phyllomeos

Make a copy of the template.cfg file and rename it

$ cp ingredients/template.cfg ingredients/extra-luanti.cfg

Add software luanti to your file:

$ nano ingredients/extra-luanti.cfg

# What ? This partial kickstart file provides the video game Luanti

%packages --exclude-weakdeps # Beginning of the packages section. Excludes weak package dependencies

luanti # a free and open-source sandbox video game

%end

Navigate inside the recipes folder:

$ cd recipes

Pick a suitable recipe to add your ingredient to it. As luanti is a GUI application, virtual-desktop.cfg is a fitting candidate. Make a copy of it.

$ cp virtual-desktop.cfg virtual-desktop-lunanti.cfg

Edit the file and add the newly defined ingredient:

$ nano virtual-desktop-luanti.cfg

%include ../ingredients/base-fedora-repo.cfg # offical repositories for Fedora
%include ../ingredients/base-storage.cfg # base storage
%include ../ingredients/base.cfg # A minimal machine
%include ../ingredients/base-desktop-gnome.cfg # A desktop environment
%include ../ingredients/base-guest-agents.cfg # Guest agents
%include ../ingredients/base-initial-setup-gnome.cfg # Includes initial-setup for GNOME Shell, allowing for the creation of a user after the first boot, as well as some basic configuration

%include ../ingredients/extra-luanti.cfg # A free and open-source sandbox video game

poweroff # Shut down the system after a successful installation

Merge the kickstart basic building blocks a single file, or dish. This process is called 'flattening'.

$ ksflatten -c virtual-desktop-lunanti.cfg -o ../dishes/virtual-desktop-luanti.cfg

If any errors are detected, go back and fix them.

If multiple dishes are affected by your ingredients, flatten them all while in the recipes folder.

for filename in *.cfg; do ksflatten -c "$filename" -o "../dishes/$filename"; done

Navigate inside the dishes folder:

$ cd ../dishes/

You can then kickstart your own installation:

# virt-install \
    --connect qemu:///system \
    --metadata description="Phyllome OS Desktop, virtual edition, with Luanti" \
    --os-variant fedora41 \
    --virt-type kvm \
    --arch x86_64 \
    --machine q35 \
    --name virtual-desktop-luanti \
    --boot uefi \
