# Bootc Debian Package Builder

A minimal repository containing the patch and deb packaging tooling to build bootc .deb packages for Debian/Ubuntu systems with libostree 2025.2-1 compatibility.

## 🎯 What This Repository Contains

- **Patch**: Fixes compatibility with libostree 2025.2-1 on Ubuntu Noble
- **Debian Packaging**: Complete debian/ directory structure
- **Build Script**: Automatically clones bootc source and builds .deb
- **Install Script**: Installs the built package with dependency handling
- **CI/CD**: Automated build pipeline for bootc packages

**Note**: The libostree 2025.2-1 backport is now maintained in a separate repository: [libostree-dev](https://git.raines.xyz/robojerk/libostree-dev)

## 🚀 Quick Start

### Prerequisites

1. **Basic build tools**: `git`, `cargo`, `rustc`, `pkg-config`
2. **Ubuntu Noble (24.04 LTS)** system

### Complete Workflow

```bash
# Clone this repository
git clone <your-repo-url> bootc-deb
cd bootc-deb

# Step 1: Install libostree 2025.2-1 backport (if not already installed)
# See: https://git.raines.xyz/robojerk/libostree-dev

# Step 2: Build the bootc .deb package
./build-bootc-deb.sh

# Step 3: Install the package
sudo ./install-bootc.sh
```

## 🔧 How It Works

### The Complete Process

1. **Requires libostree 2025.2-1** from the separate backport repository
2. **Clones bootc source** from GitHub (v1.5.1)
3. **Applies our patch** to fix libostree compatibility
4. **Installs build dependencies** automatically
5. **Builds the .deb package** using dpkg-buildpackage
6. **Copies results** to the repository directory

### The Patch

Fixes this issue in `crates/lib/src/cli.rs`:

```rust
// Before (causes build failure):
ostree::SePolicy::set_null_log();

// After (compatible):
// TODO: Re-enable when ostree Rust bindings support set_null_log()
// ostree::SePolicy::set_null_log();
```

## 🌍 Usage on Any PC

This repository is designed to work on any Ubuntu Noble system:

```bash
# On any PC in the world:
git clone <your-repo-url> bootc-deb
cd bootc-deb
# Install libostree 2025.2-1 from separate repo  # Step 1: Get required dependencies
./build-bootc-deb.sh               # Step 2: Build bootc package
sudo ./install-bootc.sh            # Step 3: Install the package
```

The complete workflow will:
- ✅ Install libostree 2025.2-1 from separate repository
- ✅ Clone bootc source from GitHub
- ✅ Apply the compatibility patch
- ✅ Install all build dependencies
- ✅ Build the .deb package
- ✅ Install the package

## 📦 Package Information

- **Package Name**: bootc
- **Version**: 1.5.1-1~noble1
- **Target**: Ubuntu Noble (24.04 LTS)
- **Dependencies**: libostree-1-1 (>= 2025.2), systemd, podman|docker.io, skopeo

## 🔗 Integration with apt-ostree

This packaging is specifically designed for Aurora-style workflow:

1. **OCI Image Compatibility**: Works with apt-ostree generated images
2. **Container Tool Integration**: Compatible with podman, skopeo
3. **System Integration**: Proper Ubuntu Noble integration
4. **Version Compatibility**: Requires libostree 2025.2-1 (automated backport included)

### Dependency Management
The libostree 2025.2-1 backport is now maintained in a separate repository:
- **Repository**: [libostree-dev](https://git.raines.xyz/robojerk/libostree-dev)
- **Automated backporting** of libostree 2025.2-1 from Ubuntu Questing
- **Safety features** including VM detection and disk space checks
- **Complete build process** with proper Debian packaging
- **CI/CD integration** for automated builds

## 🛠️ Manual Steps (if needed)

If you prefer to build manually:

```bash
# 1. Install libostree 2025.2-1 backport (if needed)
# See: https://git.raines.xyz/robojerk/libostree-dev

# 2. Clone bootc source
git clone --depth 1 --branch v1.5.1 https://github.com/containers/bootc.git bootc-1.5.1
cd bootc-1.5.1

# 3. Apply patch
patch -p1 < ../bootc-libostree-compatibility.patch

#### Manual Workflow Triggers

You can manually trigger builds in the Forgejo Actions tab:
- **Test Build**: Quick validation of bootc build process
- **Full Build**: Complete bootc package build

#### Automatic README Updates

The CI/CD automatically updates the README with download links to the latest packages:
- **Trigger**: After successful package builds
- **Content**: Direct download links to .deb files
- **Instructions**: Installation commands for users
- **Timestamp**: Shows when packages were last built

## 🎉 Success!

After installation, you'll have:

- ✅ **bootc command** available system-wide
- ✅ **Full functionality** with your apt-ostree OCI images
- ✅ **Aurora-style workflow** ready to use

## 📋 Troubleshooting

### Build Issues
- **Missing libostree 2025.2-1**: Install from [libostree-dev repository](https://git.raines.xyz/robojerk/libostree-dev)
- **Build dependencies**: The script installs them automatically
- **Git clone issues**: Check internet connection
- **Backport build failures**: See the [libostree-dev repository](https://git.raines.xyz/robojerk/libostree-dev) for troubleshooting

### Runtime Issues
- **Missing runtime dependencies**: Run `sudo apt-get install -f`
- **AppArmor denials**: Monitor with `sudo aa-logprof`

---

**Perfect for distributing bootc as .deb packages on any Ubuntu Noble system!** 🎉
