- The "Pain point: no concurrency" thing seems wrong for Nix. By default, Nix isn't using any hooks at all, and it should be concurrent. The confusion might come from the fact that NixOS does have something kind of like hooks, but nothing makes you use them. - The QEMU results are highly misleading, because there are tons of different configurations possible with QEMU. Nix builds all QEMU architectures while the Alpine one only is getting qemu-system-x86_64. It's apples to oranges. - The Nix docker image is not actually running NixOS, but instead running Alpine. It just has the Nix package manager installed on top of that.
