Oh, let me be a bit more clear. To quote the article
> The main push of docker seems to be for completely self-contained applications, basically a super cheap and consistent VM. But VMs are a hack, and docker in many ways is just as hacky.
So I just thought that the problem you have with Docker is similar to the author of the article (which is anti Docker/VM, since he dislike both).
Oh, I see. I think VMs and containers are great for different reasons. I just don't like Docker. One of the cool features of Nix is that it can manage systems on bare metal, a VM, or a container.
