Linux breaks itself all the time and is a moving target. Even in EPEL land, compatability is lacking. As this blog post said a few years ago, w32 is the only stable ABI on Linux.

That’s a good point about what the OS provides. I come from an embedded context, so often RTOS are not much more than a kernel that’s handling some basic threads and processor access. There was a really interesting talk at USENIX a few years ago (Usenix 21 keynote with Timothy Roscoe, I just looked it up) that was basically saying that a modern OS like linux, isn’t even accessing hardware and is just an OS in a system of OSs on a computer.

So you are not wrong about what you are calling bare metal, but that usage is more popular at the moment, but the older meaning of bare metal actually just means “no OS.” It’s still very common in embedded world. They are the same words, but do have different meanings.

I cannot find it at the moment, but about 10 years ago I had found a guy at Tufts (I think) who was publishing about actual bare metal (no os) single process machines that would run a server with nothing else. It was supposed to be helpful for security reasons. It was definitely whacky. I cannot find it because the server-farm usage of bare metal has taken over :(

I do now see that “bare metal server” is not going to be the right search term. Perhaps bare metal computing? I’m not sure. But what I am talking about pre-dates virtualization.

Edit: For servers, it seems the papers are calling it “Bare PC” Example: https://doi.org/10.1109/HPCC.2009.34

What you’re talking about would be called running a browser on “bare metal.” The OS is typically on charge of resource management between the various tasks. Access to the processor, storage, screen, input devices, sound, network. The os is a layer that mediates these devices. On bare metal you have to do ALL of that.

I’ve seen some interest in bare metal web servers in the past which some believe to be more secure. But I don’t think I’ve seen browsers on bare metal. There’s so much browsers need to do anymore. But anyways, bare metal would be the search terms you want to start using.

Edit: “bare metal” seems to have a newer usage for servers, so the papers I found were calling it “Bare PC.” Example: https://doi.org/10.1109/HPCC.2009.34
