[Pkg-pdns-maintainers] Bug#793593: pdns-backend-mysql: fails to remove if mysql-client is not (no longer) installed

Thank you for the thorough testing!

I think this is a bug in dbconfig-common; from a quick glance over
its documentation the pdns package does exactly what the
dbconfig-common docs say it should be doing, and nevertheless it's
now buggy.

For now I'll add the mysql-client (and other) dependencies to the
pdns package, but I'm wondering if dbconfig-common has become a
"bad smell" and extensive default configuration has become a
disservice to our users.

Cheers,
