DNS' bind 9 chrooted by default ?

[kilim]

Hello,

regarding Bind 9, here:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-bind9.html

its stated that the configuration file resides in
/var/named/etc/namedb/ and that bind will be chrooted automatically.

Yet here: 

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-dns.html

steps are shown for manual chrooting of bind (not version 9)

So I just want to confirm it with you guys, is bind 9.3 really 
chrooted by default on 5.3 ?

I mean, don't have to do any of the steps as stated in the second link, for
chrooting ?

Thank you
