su(8) in 4th edition (man page dated October 1973) contains this 
sentence:

The password demanded is that of the entry ``root'' in the system's 
password file.

First edition used /etc/uids. By third edition, /etc/uids seems to be 
deprecated (manx), and passwd(5) appears in its place (but both must be 
updated, indicating that there must still be programs relying on the 
older uids(5) format from e1). Third edition su(8) does not mention the 
name of the super-user.

Amy!

There are two major products that came out of Berkeley: LSD and BSD
Unix.  We don't believe this to be a coincidence.
