i believe that this fallback scheme is the only way you, or drc, or
florian, is able to get useful work done in this configuration. when i
ran suse linux on my laptop, dhcp-client's nameservers went into an
"include file" for BIND9, in a configuration that said "forward last;".

i do not believe that we could recommend end-user RDNS without that, or
that we should ever do so with that.
