#NixOS infra now provides a debuginfo service at https://debuginfod.nixos.org. It lets you fetch debug symbols and source code, which is super useful for getting meaningful stack traces in GDB.
This works for packages that enable separateDebugInfo. The service is powered by nixseparatedebuginfod2 created by symphorien, which is available in #nixpkgs.
