You don't need this because it's on by default :-)

You want to remove this because the DNSSEC lookaside validation service
has been decommissioned.

I prefer not to configure this or install the file, instead relying on
BIND's compiled-in copy because that means one less thing to maintain.

Each zone should have its own zsk and ksk (two K*.key and K*.private files
for each zone).

Mull of Galloway to Mull of Kintyre including the Firth of Clyde and North
Channel: Northwesterly 4 to 6 backing westerly 3 to 5, then southwesterly 2 to
4 later. Smooth or slight in far north, but elsewhere slight or moderate.
Showers, wintry at first. Good, occasionally moderate.
