From 1eeeceb9c7e52734536a4e10323634d4ada2f27e Mon Sep 17 00:00:00 2001 From: aszlig Date: Mon, 7 May 2018 03:59:38 +0200 Subject: nixos/nsd: Allow to configure root zone When trying to run NSD to serve the root zone, one gets the following error message: error: illegal name: '.' This is because the name of the zone is used as the derivation name for building the zone file. However, Nix doesn't allow derivation names starting with a period. So whenever the zone is "." now, the file name generated is "root" instead of ".". I also added an assertion that makes sure the user sets services.nsd.rootServer, otherwise NSD will fail at runtime because it prevents serving the root zone without an explicit compile-time option. Tested this by adding a root zone to the "nsd" NixOS VM test.
