[https://github.com/symphorien/nixseparatedebuginfod nixseparatedebuginfod] is a debuginfod server that can download the relevant debug outputs and source files as needed by debuginfod-capable tools. Compared to dwarffs, it does not require root access, and handles debug outputs of derivations not built by hydra (eg locally or on a custom binary cache) and source files. ~~As of~~ NixOS 22.11, ~~only hotspot~~ is built with debuginfod support by ~~default~~, ~~and notably not gdb so~~ instead of installing <code>gdb</code> in <code>/etc/nixos/configuration.nix</code>, you should install <code>(gdb.override { enableDebuginfod = true })</code>.
