+          This risks making some builds "impure" because builders sometimes
+          "canonicalise" paths by resolving all symlink components. Problems
           occur if those builds are then deployed to machines where /nix/store
           resolves to a different location from that of the build machine. You
           can enable this setting if you are sure you're not going to do that.
