📋 Detailed Workflow Steps

Step 1: Treefile Definition ✅ AVAILABLE

Tool: debian-atomic-config repository

What it does:

• Defines system variants (GNOME, KDE, Sway, Budgie, Minimal)
• Specifies package selections and dependencies
• Configures system settings and customizations

Example:

# debian-gnome-atomic.yaml
ostree:
  ref: debian/14/x86_64/gnome-atomic
  repo: /tmp/apt-ostree/debian/repo

base: debian:trixie
packages:
  - gnome-shell
  - gnome-session
  - firefox-esr

Status: ✅ COMPLETE - Repository exists with multiple variants

---

Step 2: OSTree Composition ✅ AVAILABLE

Tool: apt-ostree repository

What it does:

• Converts treefiles to OSTree commits
• Resolves Debian package dependencies
• Creates atomic system snapshots

Command:

apt-ostree compose tree treefiles/debian-gnome-atomic.yaml

Status: ✅ COMPLETE - Tool exists and functional

---

Step 3: Bootc Container Creation ✅ AVAILABLE

Tool: particle-os/bootc (Debian-compiled)

What it does:

• Converts OSTree commits to bootc containers
• Creates bootable container images
• Prepares systems for image building

Command:

bootc build --repo /path/to/ostree/repo debian/14/x86_64/gnome-atomic

Status: ✅ COMPLETE - Debian-compiled bootc available

---

Step 4: Image Building ✅ AVAILABLE

Tool: Your deb-bootc-image-builder project

What it does:

• Processes bootc containers into bootable disk images
• Creates multiple output formats (raw, qcow2, vmdk, vdi)
• Handles bootloader installation and configuration

Command:

./bib/particle-os build --base-image bootc-container recipes/desktop.yml

Status: ✅ COMPLETE - Your tool is functional

---

🎯 What We Have (Complete Ecosystem)

✅ Available Components

1. Configuration Management: debian-atomic-config

   • Multiple system variants
   • Professional configuration standards
   • CI/CD automation

2. Package Management: apt-ostree

   • Debian package → OSTree conversion
   • Dependency resolution
   • Atomic composition

3. Container Creation: particle-os/bootc

   • Debian-compiled bootc
   • OSTree → Container conversion
   • Bootable system preparation

4. Image Building: Your deb-bootc-image-builder

   • Container → Bootable image conversion
   • Multiple output formats
   • Bootloader integration

❌ What's Missing (Integration & Testing)

1. End-to-End Testing 🔄 NEEDS WORK

Missing:

• Complete pipeline validation
• Integration testing between components
• End-to-end workflow verification

What we need:

# Test complete pipeline
cd debian-atomic-config
apt-ostree compose tree treefiles/debian-minimal.yaml
bootc build --repo . debian/14/x86_64/minimal
./bib/particle-os build --base-image bootc-container recipes/minimal.yml

2. Documentation & Examples 🔄 NEEDS WORK

Missing:

• Complete workflow documentation
• User guides for the full pipeline
• Examples of complete system builds

What we need:

• Step-by-step tutorials
• Complete workflow examples
• Troubleshooting guides

3. CI/CD Integration 🔄 NEEDS WORK

Missing:

• Automated testing of complete pipeline
• Integration between repositories
• Automated builds and deployments

What we need:

• Cross-repository CI/CD
• Automated testing workflows
• Build artifact sharing

🚀 Complete Workflow Example (What Should Work)

Full Pipeline Test

# 1. Clone all repositories
git clone https://git.raines.xyz/particle-os/debian-atomic-config
git clone https://git.raines.xyz/particle-os/apt-ostree
git clone https://git.raines.xyz/particle-os/bootc

# 2. Set up development environment
cd debian-atomic-config
source dev_setup.sh

# 3. Generate OSTree commit
apt-ostree compose tree treefiles/debian-minimal.yaml

# 4. Create bootc container
bootc build --repo . debian/14/x86_64/minimal

# 5. Build bootable image
cd /path/to/your/deb-bootc-image-builder
./bib/particle-os build --base-image bootc-container recipes/minimal.yml

# 6. Test the image
qemu-system-x86_64 -hda debian-minimal.qcow2
