Hi Nix-Devs, I filed the following bug report in the Github issue tracker https://github.com/NixOS/nixpkgs/issues/25057
Hope someone has the skills to have a look at this.. I'm currently trying to work around this issue by encrypting and packaging these files myselfs and manually move the keys to the /run/keys folder.. not a nice solution but at least it should keep me going untill a fix is created.
