I guess this PR has all the relevant details / fixes https://github.com/NixOS/nix/pull/4641 somteims one can work around that bug with something like https://www.github.com/divnix/devos/tree/develop/flake.nix#L49. But this work around stops working if things are too nested. We usually use the patched nix version in a devshell to update the lock file. The correctly generated lockfile is then also compatible with a non-patched nix version.
