🎯 particle-os Recipe System

Welcome to the particle-os recipe system! This system allows you to create custom Debian-based OS images using declarative YAML recipes, similar to BlueBuild in the ublue-os ecosystem.

🌟 What is particle-os?

particle-os is a Debian-native OS image builder that creates bootable images from container images and recipes. It provides:

• Container-first workflow - Build OS from containers
• Declarative configuration - YAML-based recipes
• Multiple output formats - raw, qcow2, vmdk, vdi
• OSTree + bootupd integration - Atomic updates and bootloader management
• Debian-native stages - Built specifically for Debian

🎨 Recipe Best Practices

1. Start Simple

Begin with basic stages and add complexity gradually.

2. Use Descriptive Names

Choose clear, descriptive names for your recipes and stages.

3. Group Related Packages

Organize packages by category in your apt stages.

4. Test Incrementally

Test each stage as you build to catch issues early.

5. Document Dependencies

Include all necessary packages and their purposes.

6. Version Control

Keep your recipes in version control for collaboration.

🔍 Troubleshooting

Common Issues

Recipe Validation Fails

• Check YAML syntax
• Ensure all required fields are present
• Verify stage types are correct

Build Fails

• Check package availability in Debian repositories
• Verify target directories exist
• Check disk space availability

Image Won't Boot

• Ensure bootupd stage is included
• Verify partition configuration
• Check bootloader installation

Getting Help

• Check the recipe validation output
• Review the build logs
• Test with simpler recipes first
• Consult the particle-os documentation
