I don't know anything about how Ubuntus maintainers did created their 
named.conf layout  in detail.

The "only" configuration file each bind has / must have at least is 
named.conf 
which could be reside somewhere under /etc/ or even everywhere accessible 
from 
binds user.

All other stuff depends from how things are configured within named conf. By 
theory you could have all the config within only this single file - but this 
would be a mess in most cases.

Many bind operators are building / using their own named.conf layout on 
different OSs / distributions to make things much more flexible (i.e. i run 
DNS for different roots and different applications on different IPs for 
different IP segments from a single named and named conf by very helpful 
bind9s "views").

This is why there is no completely general config just could copied and paste 
somewhere into a named config.

This is "the Internet" or the "top zone" - each internet hostname is written 
as i.e.
                subdomain.secondleveldomain.tld.

i.e.
                host1.opennicproject.org. (see dot at the end)

i.e. try to call www.syndicat.com. or other hosts with a "."...

because every internet hostname begins from that dot regarding some rfcs no 
one has to write it today any longer to save keyclicks...

From the dot everything in the DNS hierarchy "goes down":

        . (top)
        glue. (2nd)
        opennic.glue. (3rd)
        ...

aso.

no.

it tells your bind where it has to recursively resolve against the root zone 
if it did not have/know the requested zone info by himself.
