Use live system root password for installed system

- Copy live system's root password hash directly to installed system
- Eliminates need to remember separate passwords for live vs installed
- Uses sed to replace root line in target /etc/shadow with live system hash
- Falls back to default 'mbetter123' if live password copy fails
- Maintains SSH compatibility and password authentication
