+# Raspberry Pi 4 Test Run Summary - EZ-Homelab Python Script
+## Date: 29 January 2026
+## Hardware: Raspberry Pi 4 4GB RAM, Raspberry Pi OS (Debian-based)
+## Architecture: ARM64
+
+## Executive Summary
+
+Testing the EZ-Homelab Python TUI deployment script on Raspberry Pi revealed several architecture-specific challenges and script deficiencies. While the script works on AMD64 systems, ARM64 deployment requires additional considerations and the script needs improvements in configuration file processing and deployment logic.
+
+## Key Findings
+
+### 1. Python Environment Management
+**Issue**: Direct `pip install` commands fail on modern Debian/Raspberry Pi OS due to PEP 668
+**Solution**: Must use virtual environments for all Python package installations
+**Lesson**: Script should automatically create and use virtual environments on ARM64 systems
+
+### 2. Docker Installation and Permissions
+**Issue**: Docker installation requires user group changes and system reboot
+**Solution**: Manual Docker installation + `usermod` + reboot required
+**Lesson**: Script needs to handle Docker installation with proper user permissions and reboot detection
+
+### 3. Package Architecture Compatibility
+**Issue**: Python packages must be compatible with ARM64
+**Solution**: PiWheels repository automatically provides ARM64-compatible packages
+**Lesson**: No script changes needed, but testing should include ARM64 validation
+
+### 4. Configuration File Processing
+**Issue**: Script failed to substitute environment variables in YAML configuration files
+**Solution**: Manual `sed` commands required to replace `${VARIABLE}` placeholders
+**Lesson**: Script needs robust template processing with environment variable substitution
+
+### 5. Service Deployment Logic
+**Issue**: "Core Server Only" deployment didn't include infrastructure services (Dockge)
+**Solution**: Manual deployment of infrastructure stack required
+**Lesson**: Deployment type logic needs review and testing across all scenarios
+
+### 6. Docker Network Management
+**Issue**: Required networks (`traefik-network`, `homelab-network`) not created automatically
+**Solution**: Manual `docker network create` commands required
+**Lesson**: Script should pre-create all required networks before service deployment
+
+### 7. Service-Specific Configuration Issues
+
+#### Authelia
+**Issue**: Missing required `cookies` configuration in session section
+**Solution**: Manual addition of cookies configuration
+**Lesson**: Template files need to be complete and validated against service requirements
+
+#### Sablier
+**Issue**: Configured for multi-server TLS but running on single server
+**Solution**: Changed from TCP+TLS to local socket connection
+**Lesson**: Configuration should be deployment-scenario aware (single vs multi-server)
+
+## Technical Challenges Specific to ARM64
+
+### 1. System Package Management
+- Raspberry Pi OS follows Debian's strict package management policies
+- PEP 668 prevents system-wide pip installs
+- Virtual environments are mandatory for user-space Python packages
+
+### 2. Hardware Resource Constraints
+- Limited RAM (4GB) vs typical AMD64 systems (16GB+)
+- Slower I/O and processing compared to x86_64 systems
+- Docker image pulls are slower on ARM64
+
+### 3. Architecture-Specific Dependencies
+- Some software may not have ARM64 builds
+- PiWheels provides most Python packages but not all
+- Cross-compilation issues for complex packages
+
+## Script Improvements Required
+
+### 1. Environment Setup
+```python
+# Add to script initialization
+def setup_python_environment():
+    """Create virtual environment and install dependencies"""
+    if platform.machine() == 'aarch64':  # ARM64 detection
+        # Force virtual environment usage
+        # Install dependencies within venv
+```
+
+### 2. Docker Management
+```python
+def ensure_docker_ready():
+    """Ensure Docker is installed, running, and user has permissions"""
+    # Check installation
+    # Add user to docker group
+    # Detect if reboot required
+    # Provide clear instructions
+```
+
+### 3. Configuration Processing
+```python
+def process_config_templates():
+    """Process all config templates with environment variable substitution"""
+    # Find all template files
+    # Replace ${VARIABLE} with os.environ.get('VARIABLE')
+    # Validate resulting YAML/JSON
+```
+
+### 4. Network Management
+```python
+def create_required_networks():
+    """Create all Docker networks required by services"""
+    networks = ['traefik-network', 'homelab-network']
+    for network in networks:
+        # docker network create if not exists
+```
+
+### 5. Deployment Validation
+```python
+def validate_deployment_scenario():
+    """Ensure selected services match deployment type capabilities"""
+    # Core: core services only
+    # Single: core + infrastructure + dashboards
+    # Remote: infrastructure + dashboards only
+```
+
+## Testing Recommendations
+
+### 1. Multi-Architecture Testing
+- Include ARM64 in CI/CD pipeline
+- Test on actual Raspberry Pi hardware
+- Validate PiWheels compatibility
+
+### 2. Pre-Flight Checks Enhancement
+- Add ARM64-specific system requirements
+- Check available disk space (ARM64 systems often have smaller storage)
+- Validate network connectivity for Docker pulls
+
+### 3. Error Handling Improvements
+- Better error messages for common ARM64 issues
+- Graceful handling of permission errors
+- Clear instructions for manual intervention steps
+
+## Performance Considerations
+
+### ARM64 vs AMD64 Performance
+- Docker image pulls: ~2-3x slower on ARM64
+- Python package installation: Similar performance
+- Service startup: Comparable once images are cached
+- Memory usage: More critical on ARM64 due to hardware limits
+
+### Optimization Strategies
+- Pre-pull commonly used Docker images
+- Minimize service startup time
+- Implement lazy loading where possible (Sablier)
+- Use resource limits to prevent memory exhaustion
+
+## Conclusion
+
+The EZ-Homelab Python script is functional on Raspberry Pi but requires significant improvements for production use on ARM64 systems. The main issues stem from inadequate configuration file processing and incomplete deployment logic rather than fundamental architecture incompatibilities.
+
+**Priority Improvements:**
+1. Implement proper template processing with environment variable substitution
+2. Fix deployment type logic to include all selected services
+3. Add automatic Docker network creation
+4. Enhance error handling for ARM64-specific issues
+5. Add comprehensive pre-flight checks
+
+**Testing Requirements:**
+- Dedicated ARM64 test environment
+- Automated testing of all deployment scenarios
+- Validation of all configuration file processing
+- Performance benchmarking against AMD64 systems
+
+This testing has identified critical gaps that must be addressed before the script can be considered production-ready for ARM64 deployment.</content>
