# TODO - particle-os: Debian-Native OS Image Builder

## 🎯 **Current Status: WORKING PROTOTYPE - Core Features Working, Bootable Images Created**

**Date**: August 12, 2025  
**Phase**: Phase 4 - Production Deployment & Enhancement  
**Status**: 🚧 **WORKING PROTOTYPE - Core Features Working, Bootable Images Created**

**Summary**: We have built a working bootable image builder that can extract containers, install packages, configure systems, and create bootable disk images. The images are recognized as bootable by QEMU and boot to the bootloader successfully. However, full OS boot requires kernel installation. The system is functional but needs completion for production use.
