Could you provide a timestamp of the error?

Most probably depends on https://github.com/haskell-nix/hnix-store/issues/26 to make sure this is really a performance improvement.

@7c6f434c would this be similar to https://github.com/cachix/cachix/issues/14 - where you'd use cachix only for specific project?

Sounds reasonable. About naming, I was thinking: `--print-nixos` and `--print-nix`.

It does list existing `--nixos`: ``` cachix use --help Usage: cachix use NAME [-n|--nixos] Configure nix.conf to enable binary cache during builds Available options: -h,--help Show this help text -n,--nixos...

Yes it's confusing, `--help` on top-level command lists global options and those are not repeated for each subcommand, which lists options only for itself.

And the other issue is https://github.com/pcapriotti/optparse-applicative/issues/175

I gave this a go in a704c7a4cece9ad94e41b1e8d5d2cd700ece9a78, but it's not really feasible to implement until https://github.com/NixOS/nix/issues/2149 is implemented in Nix.

@veprbl what's the use case?
