Reorganized from OneDrive export into a clean project structure: - autoinstall/: cloud-init user-data and meta-data for Ubuntu 24.04 autoinstall - playbook/: Ansible playbook for PXE server config (dnsmasq, Apache, Samba, iPXE) - unattend/: Windows unattend.xml sample for image deployment - build-usb.sh: builds a bootable USB with Ubuntu installer + CIDATA partition - download-packages.sh: downloads all offline .deb dependencies via Docker Key improvements over original: - Fully air-gapped: all packages bundled offline, no WiFi needed - Hardware-agnostic network config (wildcard NIC matching) - Removed plaintext WiFi credentials - Single USB build process (was 15+ manual steps) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
