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?
I think you could even make this into a unified kernel image [1] and boot a single image directly from EFI.<p>[1] <a href="https://wiki.archlinux.org/title/Unified_kernel_image" rel="nofollow">https://wiki.archlinux.org/title/Unified_kernel_image</a>
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.
Similar concept, but NixOS + SM64: <a href="https://xeiaso.net/blog/super-bootable-64-2020-05-06" rel="nofollow">https://xeiaso.net/blog/super-bootable-64-2020-05-06</a><p>one file, declarative, can generate an image for a physical machine, single-command boot it in Qemu, etc.<p>Well, two files, if you package SM64 yourself. Still.
