SDL display: - try SDL, auto-fallback to headless if it fails (no crash) - SDL_VIDEODRIVER=x11 to avoid wayland socket path issues - suppress XDG_RUNTIME_DIR warnings Disk copy: - zap-all before writing to clear old partition tables - delete recovery partition (4) before resizing partition 3 - use parted resizepart (preserves partition GUID for BCD) - remote: nix-shell for sgdisk/parted/ntfsresize on target - remote: lz4 compression for faster streaming - remote: pv progress bar with disk size - -y/--yes flag to skip confirmation prompt Generalize: - delay-oobe-run=true defers OOBE + activation to real hardware - clean cached Autounattend from Windows\Panther before sysprep - taskkill sysprep.exe on first login (CopyProfile artifact) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
