Thanks for your advice, Mark, but I bring bad tidings...

I've done that.  It doesn't appear, on the face of it, to make a huge
difference.  Serial 1999102807 has had all reference to ex-biff-boot
expunged, and loads without any warnings other than

Oct 28 15:54:39 [3051] Zone "20.172.IN-ADDR.ARPA" (file
ftel-lane-20.rev): No default TTL set using SOA minimum instead

and similar, which I believe to be benign.

There's a profound difference in the `no' that I get back for the
(admittedly odd, but I'm sure I'm not the only person doing it) lookup
of, for example, silver.ftel.co.uk.ftel.co.uk.

Here's the 8.1 dig talking to the 8.2.2 server:

kevin.ftel.co.uk# dig silver.ftel.co.uk.ftel.co.uk

And here it is talking to the 8.1.2 server:

kevin.ftel.co.uk# dig silver.ftel.co.uk.ftel.co.uk
