# Particle-OS: Desktop-First Immutable Ubuntu System
## Overview
Particle-OS is an immutable Ubuntu-based desktop system inspired by uBlue-OS, designed specifically for desktop users who want the benefits of atomic updates, rollback capabilities, and system integrity without the complexity of cloud-native tooling.
## Mission
Create a **desktop-first** immutable Ubuntu system that provides:
- **Simple desktop experience** - No cloud complexity, just a great desktop OS
- **Atomic updates with rollback** - Safe system updates with easy recovery
- **uBlue-OS inspiration** - Familiar patterns for users coming from Fedora-based immutable systems
- **Ubuntu ecosystem** - Full compatibility with Ubuntu software and repositories
- **Gaming and productivity focus** - Optimized for real desktop workloads
## Desktop-First Philosophy
Particle-OS is built with a simple philosophy: **desktop computing should be simple, powerful, and reliable**. We reject the complexity of cloud-native tooling for desktop users and focus on what matters most:
- **Real desktop workloads** - Gaming, development, creativity, productivity
- **Familiar workflows** - Standard desktop applications and tools
- **System reliability** - Atomic updates with easy rollback
- **User control** - Easy customization and system management
## Particle-OS Architecture

### pcore - Particle-OS Core (ucore Equivalent)
**pcore** is Particle-OS's foundational base image, equivalent to uBlue-OS's ucore. It provides the minimal, immutable foundation that all Particle-OS desktop variants build upon.
#### 1. **apt-layer** - Atomic Package Management
- Ubuntu package management with atomic transactions, live overlay system, rollback capabilities, and now true atomic OSTree commits per package operation. The new workflow supports offline .deb install, robust overlay system, and DNS fixes for WSL environments. Official ComposeFS tools are used for all image creation and mounting.

- **Desktop-Ready Base**: Pre-configured for desktop workloads and user sessions
#### 2. **composefs-alternative** - Layered Filesystem
- Content-addressable layered filesystem using overlayfs. **Note:** composefs-alternative.sh is now archived; official ComposeFS tools (`mkcomposefs`, `mount.composefs`) are used by default for all atomic package management in apt-layer. Fallback to the alternative is available if needed.
