[SunHELP] [off topic]Freebsd intel

[Big Endian]

Anybody know freebsd well?  I've been playing arround with BSD for 
the first time and I found that the  /etc/passwd includes an entry 
toor with UID 0 fullname is "bourne Again Superuser".  I just 
installed this box yesterday and the onlything running on it is the 
latest openssh.  I can't imagine how they got in as there are no 
vulnerabilities I know of in openssh 2.9.  The same entry also shows 
up in /usr/src/etc/master.passwd.  Is this a common thing in freebsd? 
I'm running 4.3-release.
