feat: complete LVM backup system with external M.2 boot support
MAJOR MILESTONE: Transform backup system into comprehensive LVM migration solution 🎯 LVM Migration & Boot System Complete: - Complete external M.2 LVM migration capability - One-button migration from non-LVM to LVM system - Automatic GRUB repair and boot configuration - External boot validation and recovery tools 🔧 New Migration Tools Added: - fix_grub_lvm_boot.sh: Complete GRUB repair for external LVM boot - automated_clonezilla_backup.sh: Automated backup with Clonezilla integration - validate_lvm_migration.sh: Comprehensive migration validation - troubleshoot_migration.sh: Advanced diagnostic and repair tools - emergency_install.sh: Package installation for live systems - bootstrap_usb_tools.sh: USB preparation with all dependencies 💾 Backup System Enhancements: - create_alpine_backup_usb.sh: Alpine Linux live system preparation - create_clonezilla_backup.sh: Professional backup solution integration - plug_and_play_backup.sh: Simple automated backup workflow - lvm_snapshot_backup.sh: LVM snapshot-based incremental backups - simple_auto_backup.sh: Streamlined backup automation 📋 Documentation & Guides: - LIVE_USB_MIGRATION_GUIDE.md: Complete migration walkthrough - DRIVE_SELECTION_REFERENCE.md: Safe drive selection procedures - Comprehensive troubleshooting and validation procedures - Step-by-step migration instructions with safety checks 🛡️ Safety & Validation Features: - Interactive drive selection with confirmation - Comprehensive pre-migration checks - Automatic backup validation - GRUB boot repair with fallback options - Hardware compatibility verification 🧪 Testing & Debugging: - Complete GRUB configuration analysis - LVM volume validation and repair - Boot sequence troubleshooting - Hardware connection diagnostics ✅ Production Ready Status: - All migration tools tested and validated - External M.2 boot functionality confirmed - GRUB configuration properly generates LVM entries - Kernel files correctly deployed to external boot partition - EFI bootloader properly configured as 'ubuntu-external' This completes the transformation from simple backup scripts to a comprehensive LVM migration and backup system capable of full system migration to external M.2 with proper boot configuration and recovery capabilities.
