I think you could even make this into a unified kernel image [1] and boot a single image directly from EFI.

Similar concept, but NixOS + SM64: https://xeiaso.net/blog/super-bootable-64-2020-05-06

one file, declarative, can generate an image for a physical machine, single-command boot it in Qemu, etc.

Well, two files, if you package SM64 yourself. Still.

Could there potentially be more applications to this approach in terms of game anticheat measures, where you boot into a unified "tournament image" which is a minimal OS that only runs the game itself for competitive sessions, as an alternative to installing intrusive kernel anticheats?

Downloads Linux Kernel 5.4.3 source and compiles it with a minimal configuration

Haha, good luck booting such a kernel.

Most minimal kernel configs are extensively tested. I've never had an issue booting from a custom kernel.

I had mostly 2 issues with custom kernels: graphics card not initialised properly (black screeen after boot, no reaction to keyboard) or X starting with missing (event ?) drivers - so no keyboard and mouse.

Good idea. I used to have a similar "boot-to-DOSBox" setup which ran on the framebuffer, it was an easy way to have a little portable gaming USB drive.

We don't really need a whole entire OS to run doom.. I want to see a port where Doom IS the OS :P
