Hey!
To manage a set of hosts, I would like to build most of their configuration at a central location but I do not want to push a full system closure for each host into the binary cache as it would allow one host to get information about another host. Instead, I want the host to complete its own configuration by combining a partial closure (a NixOS module) with its own local NixOS module. I would provide the narHash of the “common” NixOS module.
On a host, the NixOS configuration would be:
{ ... } : {
imports = [
./hardware-configuration.nix # Local to this host
./network.nix # Local to this host
./local.nix # Local to this host
./common.nix # Please use "nsvdy9ljmv80qq24nkj6gb8lgwpw29l1-nixos-system-common"
];
}
Is it possible?
