networking: Add default value for DHCP

britter · britter · commit 85334b9cfe37 · 2024-10-27T14:31:32.000+01:00
Replicates the behavior of nixos-generate-config which is to configure `useDCHP` to default to true if there are more than 0 network interfaces. See https://github.com/NixOS/nixpkgs/blob/f59db697ef71a9cbebd11cc81d87d184866382ff/nixos/modules/installer/tools/nixos-generate-config.pl#L608
