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?
