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.

nix-store --optimise to get rid of duplicate files.
This saves disk space. If set to false (the default), you can enable

periodically to get rid of duplicate files. You can also run
