Did you check /etc/master.passwd also?
Btw, what is this "src/etc/master.passwd" for?
A line like:
# $FreeBSD: src/etc/master.passwd,v 1.40 2005/06/06 20:19:56 brooks
...indicates the CVS revision that the passwd file comes from. It's
mildly interesting when you run mergemaster -iU or the like to update
to a newer version of the OS to pick up any default system accounts or
changes which have been made.
If you're instead asking why there is a /etc/passwd versus
master.passwd, the former is historically expected and is supposed to
be world-readable, but the traditional practice of putting encrypted
passwords in there made automated password cracking relatively
feasible. Various UNIXes responded to things like "John the Ripper"
by creating a second password database which contained the encrypted
passwords, called /etc/shadow in some places, or /etc/master.passwd on
FreeBSD, and having that only readable by root. The old /etc/passwd
file would then have an "x" or "*" for the passwd field.
