Is that having GCed all but the current generation of packages? Or filtering for a single nixpkgs version some other way?
Even then, I would expect NixOS to do some unsharing of shared libraries, so it would probably be best to use the full path to determine how much each shared object is actually shared.
For example, I have 87 different `libzstd.so.1` in my `/nix/store` right now.
