+
+### Common Issues
+
+#### 1. Permission Errors
+```bash
+# Ensure container has proper privileges
+docker run --privileged -v $(pwd):/workspace:z apt-ostree-ci
+```
+
+#### 2. Package Installation Failures
+```bash
+# Check repository availability
+curl -I http://deb.debian.org/debian/dists/bookworm/Release
+
+# Verify package names
+apt-cache search bash
+```
+
+#### 3. OSTree Errors
+```bash
+# Check OSTree installation
+ostree --version
+
+# Verify repository permissions
+ls -la /var/lib/ostree/
+```
+
+#### 4. Bootc Lint Failures

+```
+
+## Performance Considerations
+
+### Resource Limits
+- **Memory**: 4-8GB recommended for builds
+- **CPU**: 2-4 cores minimum
+- **Storage**: 10-20GB for temporary files
+- **Network**: Stable connection to package repositories
+
+### Build Optimization
+- **Caching**: Cache APT packages between builds
+- **Parallel builds**: Use multiple workers if possible
+- **Cleanup**: Remove temporary files after build
+- **Artifact retention**: Keep only necessary outputs
+
+## Security Notes
+
+### Container Security
+- **Privileged mode**: Required for OSTree operations
+- **Volume mounts**: Limit access to necessary directories
+- **Network access**: Restrict to required repositories only
+- **User isolation**: Run as non-root when possible
+
+### Package Security
+- **GPG verification**: Verify package signatures
+- **Repository validation**: Use trusted package sources
+- **Update frequency**: Regular security updates
+- **Vulnerability scanning**: Scan generated images
+
+## Monitoring and Logging
+
+### Build Metrics
+```bash
+# Build time tracking
+time apt-ostree compose tree treefile.yaml --container
+
+# Resource usage monitoring
+docker stats apt-ostree-ci
+
+# Output size tracking
+du -sh output/
+```
+
+### Log Analysis
+```bash
+# Parse build logs
+grep "ERROR\|WARN" build.log
+
+# Extract timing information
+grep "completed successfully" build.log
+
+# Check package installation status
+grep "installed successfully" build.log
+```
+
+## Alternative Implementations
+
+### GitLab CI
+```yaml
+build-image:
+  image: debian:bookworm-slim
+  stage: build
+  script:
+    - apt-get update && apt-get install -y ostree apt-ostree bootc
+    - apt-ostree compose tree treefile.yaml --container
+    - bootc lint output/*.tar
+  artifacts:
+    paths:
+      - output/
+    expire_in: 1 week
+```
+
+### Jenkins Pipeline
+```groovy
+pipeline {
+    agent { dockerfile true }
+    stages {
+        stage('Build') {
+            steps {
+                sh 'apt-ostree compose tree treefile.yaml --container'
+            }
+        }
+        stage('Validate') {
+            steps {
+                sh 'bootc lint output/*.tar'
+            }
+        }
+    }
+}
+```
+

+# D-Bus Infrastructure Documentation
+
+**Created**: August 21, 2024  
+**Last Updated**: August 21, 2024  
+**Status**: 🔄 In Progress - Client Infrastructure Complete
+
+## Overview
+
+The apt-ostree project includes a D-Bus infrastructure for communication between the CLI client and the system daemon (apt-ostreed). This infrastructure enables system management, transaction handling, and privileged operations.
+
+## Architecture
+
+### Service Information
+- **Service Name**: `org.projectatomic.aptostree1`
+- **Object Path**: `/org/projectatomic/aptostree1`
+- **Interface**: `org.projectatomic.aptostree1`
+- **Bus Type**: System bus (privileged operations)
+
+### Component Structure
+```
+┌─────────────────┐    D-Bus    ┌─────────────────┐
+│   CLI Client   │ ←────────→   │  apt-ostreed   │
+│  (apt-ostree)  │              │    Daemon      │
+└─────────────────┘              └─────────────────┘

+└─────────────────┘              └─────────────────┘
+```
+
+## Client Implementation
+
+### AptOstreeClient Trait
+
+The core client interface is defined by the `AptOstreeClient` trait:
+
+```rust
+#[async_trait::async_trait]
+pub trait AptOstreeClient: Send + Sync {
+    /// Start a new transaction
+    async fn start_transaction(&mut self, transaction_type: &str) -> ClientResult<String>;
+    
+    /// Get transaction status
+    async fn get_transaction_status(&self, transaction_id: &str) -> ClientResult<String>;
+    
+    /// Install packages
+    async fn install_packages(&mut self, transaction_id: &str, packages: &[&str]) -> ClientResult<bool>;
+    
+    /// Remove packages
+    async fn remove_packages(&mut self, transaction_id: &str, packages: &[&str]) -> ClientResult<bool>;
+    
+    /// Upgrade system
+    async fn upgrade(&mut self, transaction_id: &str) -> ClientResult<bool>;
+    
+    /// Rollback system
+    async fn rollback(&mut self, transaction_id: &str) -> ClientResult<bool>;
+    
+    /// Deploy new deployment
+    async fn deploy(&mut self, transaction_id: &str, refspec: &str) -> ClientResult<bool>;
+    
+    /// Rebase system
+    async fn rebase(&mut self, transaction_id: &str, refspec: &str) -> ClientResult<bool>;
+    
+    /// Get deployments
+    async fn get_deployments(&self) -> ClientResult<Vec<DeploymentInfo>>;
+    
+    /// Reload daemon
+    async fn reload(&mut self) -> ClientResult<bool>;
+    
+    /// Shutdown daemon
+    async fn shutdown(&mut self) -> ClientResult<bool>;
+}
+```
+
+### ClientDBus Implementation
+
+The `ClientDBus` struct provides the concrete implementation:
+
+```rust
+pub struct ClientDBus {
+    config: ClientConfig,
+    connection: Option<Connection>,
+    proxy: Option<AptOstreeDaemonProxy<'static>>,
+}
+```
+
+#### Key Features
+- **Connection management**: Handles D-Bus connection lifecycle
+- **Error handling**: Error types and conversion
+- **Async support**: Async/await compatibility
+- **Type safety**: Strong typing for operations
+
+## Data Structures
+
+### DeploymentInfo
+```rust
+#[derive(Debug, Clone, serde::Serialize, serde::Deserialize)]
+pub struct DeploymentInfo {
+    pub id: String,
+    pub commit: String,
+    pub booted: bool,
+    pub timestamp: String,
+    pub version: String,
+}
+```
+
+### ClientConfig
+```rust
+#[derive(Debug, Clone)]
+pub struct ClientConfig {
+    pub dbus_name: String,
+    pub dbus_path: String,
+    pub dbus_interface: String,
+    pub timeout: std::time::Duration,
+}
+```
+
+## Error Handling
+
+### ClientError Types
+```rust
+#[derive(Debug, thiserror::Error)]
+pub enum ClientError {
+    #[error("DBus error: {0}")]
+    DBus(#[from] zbus::Error),
+    
+    #[error("Connection error: {0}")]
+    Connection(String),
+    
+    #[error("Timeout error: {0}")]
+    Timeout(String),
+    
+    #[error("Authentication error: {0}")]
+    Authentication(String),
+}
+```
+
+### Error Conversion
+- Conversion from zbus errors
+- Error messages for connection issues
+- Timeout handling for operations
+- Authentication error handling
+
+## Usage Examples
+
+### Basic Client Setup
+```rust
+use apt_ostree::client::{AptOstreeClient, ClientDBus, ClientConfig};
+
+async fn setup_client() -> Result<Box<dyn AptOstreeClient>, Box<dyn std::error::Error>> {
+    let config = ClientConfig::default();
+    let mut client = ClientDBus::new(config);
+    
+    // Connect to the daemon
+    client.connect().await?;
+    
+    Ok(Box::new(client))
+}
+```
+
+### Transaction Management
+```rust
+async fn perform_upgrade() -> Result<(), Box<dyn std::error::Error>> {
+    let mut client = setup_client().await?;
+    
+    // Start upgrade transaction
+    let transaction_id = client.start_transaction("upgrade").await?;
+    println!("Upgrade transaction started: {}", transaction_id);
+    
+    // Perform upgrade
+    let success = client.upgrade(&transaction_id).await?;
+    if success {
+        println!("Upgrade completed successfully!");
+    }
+    
+    Ok(())
+}
+```
+
+### Deployment Operations
+```rust
+async fn manage_deployments() -> Result<(), Box<dyn std::error::Error>> {
+    let mut client = setup_client().await?;
+

+    for deployment in &deployments {
+        println!("Deployment: {} (commit: {})", deployment.id, deployment.commit);
+    }
+    
+    // Deploy new reference
+    let transaction_id = client.start_transaction("deploy").await?;
+    let success = client.deploy(&transaction_id, "debian/13/x86_64").await?;
+    
+    Ok(())
+}
+```
+
+## Daemon Integration
+
+### Service Configuration
+The daemon runs as a systemd service with D-Bus activation:
+
+```ini
+[Unit]
+Description=apt-ostree System Management Daemon
+Type=dbus
+BusName=org.projectatomic.aptostree1
+
+[Service]
+ExecStart=+apt-ostree start-daemon
+User=apt-ostree
+DynamicUser=yes
+```
+
+### D-Bus Interface Implementation
+The daemon implements the same interface that clients connect to:
+
+```rust
+#[interface(name = "org.projectatomic.aptostree1")]
+impl DaemonDBus {
+    fn start_transaction(&self, transaction_type: &str) -> zbus::fdo::Result<String>;
+    fn upgrade(&self, transaction_id: &str) -> zbus::fdo::Result<bool>;
+    // ... other methods
+}
+```
+
+## Security Model
+
+### Authentication
+- **Polkit integration**: Privileged operations require authentication
+- **User isolation**: Daemon runs as dedicated user
+- **Capability management**: Limited system access
+
+### Authorization
+- **Transaction validation**: All operations go through transaction system
+- **Resource limits**: Prevents resource exhaustion
+- **Audit logging**: Operation logging
+
+## Testing
+
+### Unit Tests
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    
+    #[tokio::test]
+    async fn test_client_connection() {
+        let config = ClientConfig::default();
+        let mut client = ClientDBus::new(config);
+        
+        // Test connection
+        assert!(client.connect().await.is_ok());
+    }
+}
+```
+
+### Integration Tests
+```bash
+# Test D-Bus communication
+./scripts/simple-dbus-test.sh
+
+# Python-based testing
+./scripts/test-dbus-python.py
+```
+
+## Configuration
+
+### Environment Variables
+- `DBUS_SESSION_BUS_ADDRESS`: D-Bus session bus address
+- `DBUS_SYSTEM_BUS_ADDRESS`: D-Bus system bus address
+- `RUST_LOG`: Logging level for debugging
+
+### Configuration Files
+```toml
+# apt-ostreed.conf
+[Daemon]
+DbusName = "org.projectatomic.aptostree1"
+DbusPath = "/org/projectatomic/aptostree1"
+TransactionTimeout = 300
+MaxConcurrentTransactions = 1
+```
+
+## Performance Considerations
+
+### Connection Pooling
+- **Persistent connections**: Reuse D-Bus connections
+- **Connection limits**: Prevent connection exhaustion
+- **Timeout management**: Handle slow operations gracefully
+
+### Transaction Optimization
+- **Batch operations**: Group related operations
+- **Async processing**: Non-blocking operation handling
+- **Resource cleanup**: Cleanup of completed transactions
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Connection Failures
+```bash
+# Check daemon status
+systemctl status apt-ostreed
+
+# Verify D-Bus service registration
+busctl --system list | grep aptostree
+```
+
+#### 2. Permission Errors
+```bash
+# Check Polkit policies
+ls -la /usr/share/polkit-1/actions/org.projectatomic.aptostree1.policy
+
+# Verify user permissions
+id apt-ostree
+```
+
+#### 3. Transaction Failures
+```bash
+# Check transaction logs
+journalctl -u apt-ostreed -f
+
+# Verify transaction state
+apt-ostree transaction status
+```
+
+### Debug Mode
+Enable detailed logging:
+```bash
+RUST_LOG=debug apt-ostree start-daemon
+```
+
+## Future Enhancements
+
+### Planned Features
+- **Real-time notifications**: Signal-based status updates
+- **Transaction queuing**: Multiple concurrent transactions
+- **Performance monitoring**: Metrics and profiling
+- **Plugin system**: Extensible daemon capabilities
+
+### Integration Goals
+- **Systemd integration**: Native systemd support
+- **Container support**: Kubernetes and Docker integration
+- **Monitoring**: Prometheus metrics export
+- **Security**: Enhanced authentication and authorization
+
+## Conclusion
+
+The D-Bus infrastructure in apt-ostree provides a foundation for client-daemon communication. With error handling, async support, and strong typing, it enables system management operations while maintaining security and performance.
+
+The infrastructure is designed to be extensible, allowing for future enhancements while maintaining backward compatibility and stability.

+## System Customization
 
-### Pre-Install Hooks
+### Service Management
 
-Execute commands before package installation:
+Enable systemd services:
 
 ```yaml
-spec:
-  customizations:
-    hooks:
-      pre_install:
-        - command: "mkdir -p /custom/directory"

+```yaml
+system:
+  directories:
+    - /etc/myapp
+    - /var/lib/myapp
+    - /usr/local/bin
+```
+
+### Post-Install Scripts
 
 Execute commands after package installation:
 
 ```yaml
-spec:
-  customizations:
-    hooks:
-      post_install:
-        - command: "systemctl enable custom-service"
-        - command: "update-alternatives --set editor /usr/bin/vim.basic"
+postinstall:
+  - "echo 'Custom configuration' > /etc/myapp/config.conf"
+  - "systemctl enable myapp-service"
+  - "update-alternatives --set editor /usr/bin/vim.basic"
 ```
 
 ## OSTree Integration
 
 ### Reference Management
 
-External tools should manage OSTree references properly:
+Manage OSTree references:
 
 ```yaml
-spec:
-  ostree:
-    ref: "debian/trixie/amd64/base"
-    parent_ref: "debian/trixie/amd64/base"  # For incremental builds
-    commit_message: "Custom Debian Trixie build"
-    metadata:

+  ref: "debian/trixie/amd64/myapp"
+  repo: "/srv/ostree/repo"
 ```
 
-### Delta Generation
+### Repository Structure
 
-Enable efficient updates with static deltas:
+The generated OSTree repository follows this structure:
 
-```yaml
-spec:
-  ostree:
-    generate_deltas: true
-    delta_refs:
-      - "debian/trixie/amd64/base"
-      - "debian/trixie/amd64/base"

 ## Error Handling
 
 ### Common Issues
 
-1. **Invalid Package Names**: Check package existence before inclusion
-2. **Missing Dependencies**: Ensure all required packages are specified
-3. **OSTree Conflicts**: Handle reference conflicts gracefully
-4. **Permission Issues**: Validate file paths and permissions
+1. **Invalid Package Names**: Check package existence in repositories
+2. **Repository Access**: Ensure package sources are accessible
+3. **Permission Issues**: Verify write access to OSTree repository

+## Current Status
+
+### **Bootc Image Generation - Working**
+The project has implemented a bootc image generation system that:
+- Creates OCI-compatible container images from OSTree trees
+- Generates Docker archives that load and run
+- Provides workflow from treefile to image
+- Achieves compatibility with bootc and container runtimes
+
+### **D-Bus Infrastructure - In Progress**
+A D-Bus communication system is being implemented for:
+- Client-daemon communication
