The only thing it looks like you would have to change is one option

directory "/etc/namedb";
would be
directory "/var/named";

And the way you start, stop, and restart named (the linux method is different from the BSD method.
I have actually used this site as a reference to help me setup DNS on a Linux box. It is worth a read-over.
