Describe the bug

The docker-tools test is broken.

To Reproduce
Steps to reproduce the behavior:

$ nix-build nixos/tests/docker-tools.nix
# ...
error: command `docker run --rm nix nix-store -qR /nix/store/xiqgdw8s05szign92b7q3mc1yvnkz8gx-nix-2.3.1' did not succeed (exit code 1)

The command before (loading the image) worked well but the failing command has no output. With my limited knowledge about docker i was not able to find out, why.
