querying x is displayed instead of actual hash

[SuperSandro2000]

When running the tool on a skyflake nix store I always get querying x on file:///storage/cephfs/store where x should probably be what currently is being queried, right?

This is because Nix doesn't know the name of the path before reading the narinfo. Related: NixOS/nix#5645

I suppose we could redirect its stderr to /dev/null so it doesn't report that nonsense. Personally I don't care enough to change this, but if you want to do that in a PR I'm happy to merge it.
