Since nix 2.20, `nix-store --add-fixed` doesn't accept paths where the parent directory is a symlink. On macOS, /tmp is a symlink to /private/tmp, which causes a "'/tmp' is a symlink" error: ``` $ nix run github:nixos/nixpkgs/24.11-beta#nix-prefetch-git -- --url https://github.com/IFTTT/polo.git --rev 316aa2ac210a45a7fc400ab921831493d5dd21b8 --hash sha256 Initialized empty Git repository in /private/tmp/git-checkout-tmp-1Bf9bIv7/polo-316aa2a/.git/ remote: Enumerating objects: 51, done. remote: Counting objects: 100% (51/51), done. remote: Compressing objects: 100% (42/42), done. remote: Total 51 (delta 8), reused 19 (delta 5), pack-reused 0 (from 0) Unpacking objects: 100% (51/51), 19.57 KiB | 541.00 KiB/s, done.
