				     I don't think your master is called bozo.0.0.127.in-addr.arpa., =
no?
				     as this is a reverse zone, you will need to use FQDNs for =
these, else it
				     will the origin, which is not what you want here.

I personally think expire values should be larger than 1W to be able to
survive longer absences (conferences etc) of the admin :-)

Same comment about the origin here !!

Sure, you did not have $TTL at the top of the zonefile, nor an explicit =
TTL
on the SOA record !
