on Debain bullseye file_bindkeys is not '/etc/named.iscdlv.key'

[fayeg21]

In params you assume $file_bindkeys = '/etc/named.iscdlv.key' but on Debian bullseye this value should be /etc/bind/bind.keys

ATM this is not overridable in your module AFAICS.

ATM this is making it non-trival to use your module to configure bind.
