Fine, I ran the whole thing against known configs of my own. Have at it.

What came from user-level, is below. Can't be bothered to do root-user 
separation.

[~] vim at workstation.vm.ideapad.lan
[$] /bin/bash scp root at dns.vm.ideapad.lan:/etc/bind/named.conf /tmp/named.conf
named.conf                                    100% 3159   968.9KB/s   00:00

Activisme is pas nuttig, wanneer het kan bereiken wat het wenst te bereiken,
