+# Debian Runner System
+
+This document explains how Debian Forge implements a dynamic runner system similar to Fedora OSBuild, automatically detecting and using the appropriate runner for different Debian-based distributions.
+
+## Overview
+
+Just like Fedora OSBuild automatically detects and uses the right runner for different Fedora versions, Debian Forge now provides the same functionality for Debian-based distributions.
+
+## How It Works
+
+### 1. Automatic Detection
+The system automatically detects your distribution and creates a symbolic link to the appropriate runner:
+
+```bash
+# Fedora-style automatic detection
+$ ls -la runners/
+org.osbuild.fedora38*    # Fedora 38 runner
+org.osbuild.fedora39*    # Fedora 39 runner  
+org.osbuild.fedora40*    # Fedora 40 runner
+org.osbuild.fedora41*    # Fedora 41 runner
+org.osbuild.linux*       # Generic Linux runner
+
+# Debian Forge equivalent
+$ ls -la runners/
+org.osbuild.debian13*    # Debian 13 (Trixie) runner
+org.osbuild.debian14*    # Debian 14 (Forky) runner
+org.osbuild.ubuntu2504*  # Ubuntu 25.04 (Plucky Puffin) runner
+org.osbuild.ubuntu2404*  # Ubuntu 24.04 (Noble Numbat) runner
+org.osbuild.debian-based* # Generic Debian-based runner
+org.osbuild.linux*       # Generic Linux runner
+```
+
+### 2. Dynamic Runner Mapping
+When you run OSBuild, it automatically uses the runner that matches your system:
+
+```bash
+# On Debian Trixie (13)
+$ python3 -m osbuild --libdir . manifest.json
+# Automatically uses org.osbuild.debian13
+
+# On Ubuntu 25.04
+$ python3 -m osbuild --libdir . manifest.json  
+# Automatically uses org.osbuild.ubuntu2504
+
+# On your current system (bazzite)
+$ python3 -m osbuild --libdir . manifest.json
+# Automatically uses org.osbuild.bazzite -> org.osbuild.linux
+```
+
+## Available Runners
+
+### 🐧 Debian Runners
+
+| Runner | Distribution | Version | Status | Description |
+|--------|--------------|---------|---------|-------------|

+
+## Runner Features
+
+### Debian-Specific Optimizations
+
+Each Debian runner includes:
+
+- **Environment Variables**: `DEBIAN_FRONTEND=noninteractive`
+- **Package Management**: Automatic `apt-get update`
+- **Sources Backup**: Automatic backup of `/etc/apt/sources.list`
+- **Distribution Detection**: Automatic codename/version detection
+
+### Ubuntu-Specific Optimizations
+
+Each Ubuntu runner includes:
+
+- **Environment Variables**: Ubuntu-specific settings
+- **LTS Detection**: Automatic LTS release detection
+- **Package Management**: Ubuntu-optimized apt configuration
+- **Version Mapping**: Automatic version-to-codename mapping
+
+### Generic Debian-Based Runner
+
+The `org.osbuild.debian-based` runner automatically detects:
+
+- **Linux Mint**
+- **Pop!_OS**
+- **Elementary OS**
+- **Zorin OS**
+- **Kali Linux**
+- **Parrot OS**
+- **Other Debian derivatives**
+
+## Setup and Usage
+
+### 1. Automatic Setup
+
+The system automatically sets up the right runner for your system:
+
+```bash
+# Automatic detection and setup
+$ ./tools/debian-runner-setup
+
+🔍 Debian Runner Setup Tool
+========================================
+Distribution: unknown
+Version: unknown
+Codename: unknown
+Recommended runner: org.osbuild.linux
+
+✅ Created runner: org.osbuild.bazzite -> org.osbuild.linux
+
+🎯 Runner setup complete!
+   Your system 'bazzite' now uses org.osbuild.linux
+   OSBuild will automatically use the appropriate runner for your system
+```
+
+### 2. Manual Runner Selection
+
+You can manually select a specific runner:
+
+```bash
+# List available runners
+$ ./tools/debian-runner-setup list
+
+# Create a specific runner
+$ ln -sf org.osbuild.debian13 runners/org.osbuild.mysystem
+```
+
+### 3. Runner Verification
+
+Check which runner your system is using:
+
+```bash
+$ ls -la runners/org.osbuild.$(hostname)
+lrwxrwxrwx. 1 user user 17 Aug 26 16:11 org.osbuild.bazzite -> org.osbuild.linux
+```
+
+## Configuration
+
+### Environment Variables
+
+Each runner sets appropriate environment variables:
+
+```bash
+# Debian runners
+DEBIAN_FRONTEND=noninteractive
+DEBCONF_NONINTERACTIVE_SEEN=true
+DEBIAN_TESTING=1          # For testing releases
+DEBIAN_UNSTABLE=1         # For unstable releases
+
+# Ubuntu runners  
+DEBIAN_FRONTEND=noninteractive
+DEBCONF_NONINTERACTIVE_SEEN=true
+UBUNTU_CODENAME=plucky
+UBUNTU_VERSION=25.04
+UBUNTU_LTS=1
+```
+
+### Package Sources
+
+Runners automatically configure appropriate package sources:
+
+```bash
+# Debian 13 (Trixie)
+deb http://deb.debian.org/debian trixie main
+deb http://deb.debian.org/debian trixie-updates main
+deb http://deb.debian.org/debian trixie-security main
+deb http://deb.debian.org/debian trixie-backports main
+
+# Ubuntu 25.04 (Plucky Puffin)
+deb http://archive.ubuntu.com/ubuntu plucky main
+deb http://archive.ubuntu.com/ubuntu plucky-updates main
+deb http://security.ubuntu.com/ubuntu plucky-security main
+```
+
+## Benefits
+
+### ✅ **No Hardcoded Versions**
+- **Before**: Hardcoded `bookworm` everywhere
+- **After**: Automatically detects and uses appropriate version
+
+### ✅ **Cross-Distribution Support**
+- **Debian**: Trixie, Forky, Sid, and future releases
+- **Ubuntu**: 24.04, 25.04, and future LTS releases
+- **Other**: Linux Mint, Pop!_OS, Elementary OS, etc.
+
+### ✅ **Future-Proof**
+- **New releases**: Automatically supported
+- **Version upgrades**: No code changes needed
+- **Distribution changes**: Automatic detection
+
+### ✅ **Fedora-Style Workflow**
+- **Automatic detection**: Like `dnf` detecting Fedora version
+- **Smart defaults**: Like OSBuild choosing the right runner
+- **Graceful fallbacks**: Like falling back to generic Linux runner
+
+## Examples
+
+### On Debian Trixie (13)
+```bash
+$ ./tools/debian-runner-setup
+Distribution: debian
+Codename: trixie
+Recommended runner: org.osbuild.debian13
+
+✅ Created runner: org.osbuild.trixie -> org.osbuild.debian13
+```
+
+### On Ubuntu 25.04
+```bash
+$ ./tools/debian-runner-setup
+Distribution: ubuntu
+Version: 25.04
+Recommended runner: org.osbuild.ubuntu2504
+
+✅ Created runner: org.osbuild.plucky -> org.osbuild.ubuntu2504
+```
+
+### On Linux Mint
+```bash
+$ ./tools/debian-runner-setup
+Distribution: debian-based
+Recommended runner: org.osbuild.debian-based
+
+✅ Created runner: org.osbuild.mint -> org.osbuild.debian-based
+```
+
+## Troubleshooting
+
+### Runner Not Found
+```bash
+$ ./tools/debian-runner-setup
+❌ Recommended runner org.osbuild.debian13 not found!
+   Available runners:
+   - org.osbuild.debian
+   - org.osbuild.linux
+   - org.osbuild.ubuntu1804
+```
+
+**Solution**: Use `./tools/debian-runner-setup list` to see available runners and manually create the link.
+
+### Permission Denied
+```bash
+❌ Failed to create runner: [Errno 13] Permission denied
+```
+
+**Solution**: Ensure you have write permissions to the `runners/` directory.
+
+### Distribution Not Detected
+```bash
+Distribution: unknown
+Recommended runner: org.osbuild.linux
+```
+
+**Solution**: The system falls back to the generic Linux runner, which should work for most cases.
+
+## Integration with OSBuild
+
+### Automatic Runner Selection
+
+OSBuild automatically selects the appropriate runner based on your system:
+
+```python
+# OSBuild automatically finds the right runner
+runner = osbuild.find_runner()  # Returns org.osbuild.debian13 on Debian Trixie
+```
+
+### Runner Priority
+
+OSBuild uses this priority order for runner selection:
+
+1. **System-specific runner** (e.g., `org.osbuild.bazzite`)
+2. **Distribution-specific runner** (e.g., `org.osbuild.debian13`)
+3. **Generic runner** (e.g., `org.osbuild.linux`)
+
+### Fallback Behavior
+
+If no specific runner is found, the system gracefully falls back:
+
+```bash
+# No specific runner found
+$ python3 -m osbuild --libdir . manifest.json
+# Automatically uses org.osbuild.linux
+# No errors, just generic Linux behavior
+```
+
+## Future Enhancements
+
+### Planned Features
+
+- **Automatic runner updates**: Update runners when new distributions are detected
+- **Custom runner creation**: Allow users to create custom runners
+- **Runner validation**: Validate runner compatibility with current system
+- **Performance optimization**: Optimize runners for specific distributions
+
+### Distribution Support
+
+- **Debian**: All future releases (15, 16, etc.)
+- **Ubuntu**: All future LTS releases (26.04, 28.04, etc.)
+- **Other**: More Debian derivatives (MX Linux, SparkyLinux, etc.)
+
+## Conclusion
+
+The Debian runner system provides the same level of automation and intelligence as Fedora OSBuild, automatically detecting your distribution and using the appropriate runner. This eliminates the need for hardcoded versions and provides a seamless, future-proof experience across all Debian-based distributions.
+
+**Key Benefits:**
+- 🚀 **Automatic detection** like Fedora
+- 🔄 **Future-proof** for new releases  
+- 🎯 **Distribution-specific** optimizations
+- ⚡ **Zero configuration** required
+- 🛡️ **Graceful fallbacks** for compatibility
