Symlinking works for most plugins and themes, but Avada, for instance, fails to understand the symlink, causing its file path stripping to fail. This results in requests that look like: https://example.com/wp-content//nix/store/...plugin/path/some-file.js Since hard linking directories is not allowed, copying is the next best thing.
