feat: Complete ISO build system with security features
Major updates for production-ready ISO:
1. **Debian Version**:
- Updated to Debian 13.3.0 stable (released)
- No longer using testing/sid
- Using debian:stable Docker image
2. **Password Complexity Enforcement**:
- Added libpam-pwquality and libpwquality packages
- Password complexity enforced during install via PAM
- Configured in security-config.sh:
* Minimum 12 characters
* Mixed case required
* At least one digit
* At least one special character
* 3 character classes required
- Preseed enforces password checks during installer
3. **Auto-Lock After 1 Minute**:
- Added xautolock and xscreensaver packages
- Configured in .xinitrc for auto-lock after 1 minute idle
- Uses xscreensaver-command -lock for screen locking
4. **USB Drive Mounting**:
- Added udisks2, gvfs-backends, gvfs-fuse packages
- Created polkit rules for USB mounting
- User added to plugdev and cdrom groups
- USB drives mountable via file manager
5. **WiFi and Bluetooth Disabling**:
- Created config/disable-wifi-bt.sh script
- Blacklists all WiFi kernel modules
- Blacklists all Bluetooth kernel modules
- Masks bluetooth service
- Removes bluez packages
6. **First-Boot Verification**:
- Created scripts/verify-system.sh
- Created config/football-first-boot.service
- Verifies all functional requirements
- Runs once on first boot
- Prevents re-running via status file
7. **ISO Build System**:
- Updated to use Debian 13.3.0 stable ISO
- Scripts and config baked into ISO
- Docker-based build process
- Corrected ISO filename throughout
8. **Preseed Configuration**:
- Manual user creation (not automated)
- Manual password prompts (enforced via PAM)
- Late_command applies all security configs
- Copies verification script to target
- Enables first-boot verification service
Files Added:
- config/disable-wifi-bt.sh (WiFi/BT disabling)
- config/security-config.sh (password complexity, auto-lock, USB mounting)
- config/football-first-boot.service (first-boot verification systemd service)
- scripts/verify-system.sh (comprehensive verification script)
Files Updated:
- config/preseed.cfg (password enforcement, security packages, late_command)
- scripts/build-iso.sh (Debian 13.3.0, correct filenames)
- docs/FUNCTIONAL-REQUIREMENTS.md (verification strategy)
- AGENTS.md (documentation references)
- README.md (documentation references)
All requirements from this session implemented:
✓ Password complexity enforced during install
✓ Auto-lock after 1 minute idle
✓ USB drive mounting enabled
✓ WiFi/Bluetooth disabled
✓ First-boot verification
✓ Scripts baked into ISO (no internet needed)
✓ All packages in ISO
✓ Debian 13.3.0 stable
