I am assuming that IBM wasn't aware of the sysadmin who leave the console
for a few minutes. Linux also has this ''problem''. I suspect since the
passwd code was designed so that root could change any users passwd,
therewasn't a provision to check to see if root was changing root's passwd.
Still. This could be easily bypassed by simply editing the /etc/passwd file.
Setting the passwd field to null.
