- Replace agetty --autologin with traditional getty -a root syntax
- Remove bash expansion {2..6} and use explicit tty entries
- Remove linux parameter that may not be supported in older systems
- Use standard 38400 baud rate format
- Ensure compatibility with traditional SysV init systems

Traditional SysV inittab entries now:
1:23:respawn:/sbin/getty -a root 38400 tty1  # Autologin
2:23:respawn:/sbin/getty 38400 tty2          # Normal login
3:23:respawn:/sbin/getty 38400 tty3          # Normal login
...etc

- tty2-6: Normal login shells for debugging access
- SSH: Uses root password from ISO creation (not hardcoded)
- Installed system: Auto-login + OpenVPN + MBetterClient with --web-host 0.0.0.0

Tools Added:
- extract_iso.sh / rebuild_iso.sh: Immediate ISO modification workflow
