\How'd you do that? In the absence of a password file entry for root
\will su _really_ let you in? [ The answer in SVr[12?] is NO ]
Think 1 step further:
% ls -l /etc/passwd
-rw-r--r-- 1 root 97 Apr 3 23:59 /etc/passwd
This passwd file probably contains an incomplete line, and we all know how
getpwnam() and friends (used to) treat such lines, don't we?
Remember the "Comments in /etc/passwd" discussion?
