so, about nixos-unstable in your config — just add an unstable channel to system via
```
sudo nix-channel --add nixos-unstable https://nixos.org/channels/nixos-20.03
```
and then use it in your config like that
```
let pkgsUnstable = import <nixos-unstable> {}; in
  [ pkgsUnstable.nmap pkgsUnstable.tor ]
