For the channels look into https://github.com/NixOS/nixpkgs-channels. The branches here map directly to the channels that you can fetch publicly. If you figure out which files are being used by nfs then it's a matter of running a diff between the different branches.
https://github.com/NixOS/nixpkgs-channels/blob/nixos-16.09/nixos/modules/services/network-filesystems/nfsd.nix doesn't seem to have changed since 16.03. It seems to be using the nfs-utils which you can find in the pkgs/top-level/all-packages.nix and follow from there. nfs-utils seems to have changed: https://github.com/NixOS/nixpkgs-channels/blob/nixos-16.09/pkgs/os-specific/linux/nfs-utils/default.nix There is also the kernel module that you might want to dig into. I know it's not a direct solution but hopefully it will give you some more things to try out.
