If set to true, Nix automatically detects files in the store that have identical contents, and replaces them with hard links to a single copy. This saves disk space. If set to false (the default), you can enable nix.optimise.automatic to run nix-store --optimise periodically to get rid of duplicate files. You can also run nix-store --optimise manually.
