Particle-OS rebranding from uBlue-OS - Professional installation system with standardized paths - Self-initialization system with --init and --reset commands - Enhanced error messages and dependency checking - Comprehensive testing infrastructure - All source scriptlets updated with runtime improvements - Clean codebase with redundant files moved to archive - Complete documentation suite ---

Quick development install +sudo ./dev-install.sh +``` + +## What Gets Installed + +The installation script installs the following tools to `/usr/local/bin/`: + +| Source Script | Installed As | Purpose | +|---------------|--------------|---------| +| `apt-layer.sh` | `apt-layer` | Package layer management | +| `composefs-alternative.sh` | `composefs` | ComposeFS image management | +| `bootc-alternative.sh` | `bootc` | Bootable container management | +| `bootupd-alternative.sh` | `bootupd` | Bootloader management | +| `orchestrator.sh` | `particle-orchestrator` | System orchestration | +| `oci-integration.sh` | `particle-oci` | OCI integration | +| `particle-logrotate.sh` | `particle-logrotate` | Log rotation management | + +**Note**: The `fsverity` command is provided by the Ubuntu `fsverity` package and should be installed separately: +```bash +sudo apt install -y fsverity +``` + +## Configuration + +The installation script also installs: +- `particle-config.sh` β†’ `/usr/local/etc/particle-config.sh` + +## Post-Installation Setup + +After installation, initialize the Particle-OS system: + +```bash +# Install system dependencies (if not already installed) +sudo apt install -y fsverity + +# Initialize the system +sudo apt-layer --init + +# Verify installation +particle-orchestrator help +``` + +## Verification + +Check that all tools are properly installed: + +```bash +# Check if tools are in PATH +which apt-layer +which composefs +which bootc +which bootupd +which particle-orchestrator + +# Test basic functionality +apt-layer --help +composefs --help +particle-orchestrator help +``` + +## Uninstallation + +To completely remove Particle-OS tools: + +```bash +# Remove all installed scripts +sudo rm -f

if desired: +# sudo apt remove fsverity + +## Backup and Recovery + +The installation script automatically creates backups of existing installations: + +- Backups are stored as `script.backup.YYYYMMDD_HHMMSS` +- Example: `/usr/local/bin/apt-layer.backup.20250127_143022` + +To restore from backup: + +```bash +# List available backups +ls -la /usr/local/bin/*.backup.* + +#

+```bash +# Ensure script is executable +chmod +x install-particle-os.sh + +# Run with sudo +sudo ./install-particle-os.sh +``` + +### Script Not Found +```bash +# Check if script exists in current directory +ls -la *.sh + +# Ensure you're in the correct directory +pwd +``` + +### PATH Issues +```bash +# Check if /usr/local/bin is in PATH +echo $PATH | grep /usr/local/bin + +# Add to PATH if needed (add to ~/.bashrc or ~/.profile) +export PATH="/usr/local/bin:$PATH" +``` + +### Configuration Issues +```bash +# Check if configuration is installed +ls -la /usr/local/etc/particle-config.sh + +# Reinstall configuration +sudo cp particle-config.sh /usr/local/etc/ +``` + +## Development Workflow + +For developers working on Particle-OS: + +1. **Make changes** to scripts in the project directory +2. **Quick reinstall** with `sudo ./dev-install.sh` +3. **Test changes** with the installed tools +4. **Repeat** as needed + +The development install script skips backups and verification for faster iteration. + +## System Requirements + +- Linux system (Ubuntu/Debian recommended) +- Root access (sudo) +- Bash shell +- Basic system utilities (cp, chmod, chown, etc.) +- fsverity package (for file integrity verification) + ```bash + sudo apt install -y fsverity + ``` + +## Next Steps + +After installation: + +1.
