It takes some extra 13MB (and in dev, not out), but allows perf to show kernel
symbols when profiling. I think it is worth it.
In my NixOS, I refer to it in the system derivation, for easy telling to perf
through /run/booted-system/vmlinux:
system.extraSystemBuilderCmds = ''
ln -s ${config.boot.kernelPackages.kernel.dev}/vmlinux $out/vmlinux
'';
