$ nix-instantiate /etc/nixos/nixos -A system
warning: you did not specify `--add-root'; the result might be removed by the garbage collector
/nix/store/8vpxk1df3zc4c9l8mv4fj32ma173nm4g-system.drv 

The warning can be ignored I assume, given that no changes were made to
configuration.nix, nixpkgs, nixos since the last nixos-rebuild.


$ nix-store -q --deriver $(nix-instantiate /etc/nixos/nixos/ -A system)
warning: you did not specify `--add-root'; the result might be removed by the garbage collector
unknown-deriver

NOTE: --deriver is not listed by 'nix-store --help', but documented in
the man page.

However, I don't know how to fix that command line.
