As a matter of fact, the next release of System V has a "shadow" password
file to complement /etc/passwd.  It is not readable by the world.  The
passwords in /etc/passwd are dummies (the string ":np:" or whatever the
password was in /etc/passwd prior to conversion).

Should put an end to password hacking as we know it :-)
