- ✅ **OSTree Repository Operations**: Initialize, commit, checkout working
- ✅ **Package Operations**: List, search, install simulation working
- ✅ **OCI Image Generation**: From real OSTree commits working
- ✅ **Bootc-Compatible Images**: Proper OCI structure with bootc labels
- ✅ **Deployment Simulation**: Checkout and deployment management working
- ✅ **Rollback Simulation**: Rollback point creation and management working
- ✅ **System Upgrade Simulation**: Upgrade workflow working
### **Key Features**
- **Atomic Updates**: Package installations and updates are atomic - they either complete fully or rollback completely
- **OSTree Integration**: Seamless integration with OSTree for system image management
- **APT Compatibility**: Familiar APT commands and package management workflow
- **Dependency Resolution**: Advanced dependency resolution with conflict detection
- **Security**: Sandboxed package operations using bubblewrap
### 🔄 **CURRENT DEVELOPMENT PHASE**
### **Use Cases**
- **Immutable Infrastructure**: Deploy and manage immutable server images
- **Atomic Desktop Updates**: Update desktop systems atomically
- **Container Base Images**: Manage package layers in container base images
- **System Rollbacks**: Easy system rollbacks to previous states
#### **End-to-End Workflow Testing**
- ✅ **Complete Aurora-Style Workflow**: From package installation to OCI deployment
- ✅ **Real OSTree Environment**: Working with actual OSTree repositories
- ✅ **OCI Image Validation**: Image generation and inspection working
- ✅ **Bootc Integration**: Compatible image generation working

# Clone repository
git clone https://github.com/your-org/apt-ostree.git
cd apt-ostree
# Install a package atomically
apt-ostree install nginx
# Build
cargo build --release
# Check system status
apt-ostree status
# Rollback if needed
apt-ostree rollback
```
## 🔧 **System Requirements**
- **Operating System**: Debian 13 (Trixie) or Ubuntu 24.04 (Noble) or later

## 📦 **Installation**
### **From Debian Package**
```bash
# Download the latest package
wget https://github.com/particle-os/apt-ostree/releases/latest/download/apt-ostree_amd64.deb
# Install
sudo ./apt-ostree-complete-fix.sh
sudo dpkg -i apt-ostree_amd64.deb

# Test full workflow
sudo apt-ostree install package-name
```
## Bootc Integration
### Why Bootc?
Bootc is essential for the **Aurora-style workflow** - a modern approach to system deployment that treats operating systems as container images. This enables:
- **Container-native deployments**: Deploy systems like containers
- **Atomic updates**: Transactional system updates with rollback
- **Immutable infrastructure**: Predictable, reproducible deployments
- **Cloud-native workflows**: Integration with container registries and CI/CD
### Installing Bootc
Bootc is available as a Debian package from the Forgejo repository:
```bash
# Add the Forgejo repository
curl -fsSL https://git.raines.xyz/api/packages/robojerk/debian/repository.key | sudo gpg --dearmor -o /usr/share/keyrings/forgejo-robojerk.gpg
echo "deb [signed-by=/usr/share/keyrings/forgejo-robojerk.gpg] https://git.raines.xyz/api/packages/robojerk/debian noble main" | sudo tee /etc/apt/sources.list.d/forgejo-robojerk.list
# Update package lists
sudo apt update
# Install libostree 2025.2-1 packages (required dependency)
sudo apt install -y libostree-dev=2025.2-1~noble1 libostree-1-1=2025.2-1~noble1
# Install bootc
sudo apt install -y bootc
```
### Aurora-Style Workflow with apt-ostree
The complete Aurora-style workflow combines apt-ostree and bootc:
```bash
# 1. Create OSTree commit with apt-ostree
sudo apt-ostree install nginx apache2
# 2. Build OCI image from commit
apt-ostree compose build-chunked-oci --rootfs /var/lib/apt-ostree/repo --output my-system:latest --bootc
# 3. Deploy with bootc
bootc install oci:my-system:latest
# 4. Boot into new deployment
bootc status
```
### Bootc Package Repository
The bootc package is maintained in a separate repository:
- **Repository**: [bootc-deb](https://git.raines.xyz/robojerk/bootc-deb)
- **Package**: [bootc 1.5.1-1~noble1](https://git.raines.xyz/robojerk/-/packages/debian/bootc/1.5.1-1~noble1)
- **Dependencies**: libostree-1-1 (>= 2025.2), systemd, podman|docker.io, skopeo
