readNixpkgSet doesn't record multiple attributes for the same derivation

This is an inherent problem of using nix-env: This tool lists unique derivation and additional information, like their name or attribute path. As a result every derivation will only be listed once with one attribute path (it seems the one that comes first in an alphanumeric sort is used).

This is an issue if we are more interested in attributes than derivations: If we resolve "pam", we'll get python38Packages.pam as the shortest identifier despite the expected solution being just pam. This happens because on Linux pam == linux-pam and nix-env only displays one of those attributes.

This should be fixable, but it will require a bit of refactoring (since we won't be able to achieve what we want with nix-env in a clean way). I'll try to send a PR in the near future.

Status of the repository?

Hi,

As part of NixOS/teams-collaboration#1, I am trying to clarify the status of the repositories under the NixOS organisation.

This repository seems to be unmaintained or obsolete, so it will be archived in a month.

If you think it warrants staying here or should be moved to another organization instead, please answer this issue.
