Comment: The upstream code is ambiguous about whether the license is
 LGPL-2.1 or LGPL-2.1+, see https://github.com/NixOS/nix/issues/3390.
 README.md says: "Nix is released under the LGPL v2.1".
 nix.spec.in and about-nix.xml say "LGPL 2.1+".
 Thus leaving the more conservative choice here until upstream resolves
 this.
