Up to now the system has been operating in single-user mode. There is no login process and anyone who boots the system goes straight into a shell with root privileges. Obviously, this is not the normal operating mode for most GNU/Linux distributions. Most systems feature multi-user capability where many users can access the system simultaneously with different privilege levels. These multi-user systems also support virtual consoles so that the keyboard and video display can be multiplexed between several terminal sessions. So in this phase we would like to add the following enhancements to the system:
Enable multi-user capability.
Create multiple, virtual consoles.
