[Pkg-dns-devel] Bug#865561: pdns_server does not start after upgrade to stretch

[Juha Heinanen]

Package: pdns-server
Version: 4.0.3-1

In Jessie, I had these packages installed:

$ dpkg -l | egrep pdns
ii  pdns-backend-mysql                    3.4.1-4+deb8u7                    amd64        generic MySQL backend for PowerDNS
ii  pdns-recursor                         3.6.2-2+deb8u3                    amd64        PowerDNS recursor
ii  pdns-server                           3.4.1-4+deb8u7                    amd64        extremely powerful and versatile nameserver

Upgrade from Jessie to Stretch also installed pdns-backend-bind, which
resulted in failed start of pdns_server:

pdns Fatal error: Trying to set unknown parameter 'bind-config'

I was able to get rid of the error by removing
/etc/powerdns/pdns.d/bind.conf.

I don't understand why pdns-backend-bind was installed, since it is not
required, but only recommended by pdns-server:

rec: pdns-backend-bind

How can I get the upgrade done without installation of
pdns-backend-bind?
