That's way easier:

Add a home dir and a useful shell to SYSTEM's /etc/passwd entry:

  SYSTEM:*:18:544:,S-1-5-18:/home/system:/bin/bash

Then:  Install sshd as service, create a private/public key pair, put
the public key into /home/system/.ssh/authorized_keys and login to your
system using `ssh -l system localhost'.

Or:  Install inetd as service, remove the `*' from SYSTEM's password
field and login to localhost using rlogin or telnet.
