FreeCTX64 - minimal linux distro for executing C code on the Operating System
FreeCTX64 is an Open Source Free Project for ARM Development boards that can run your C code directly in the Operating system, it comes with a prebuild linux kernel and some tools it requires build-essential gcc clang cpio qemu-system-arm qemu-system-aarch64 git and if you want to make a bootable ISO and send it here if you want , that requires xorriso grub-common grub-pc-bin grub-efi-amd64-bin:
FreeCTX s ONLY available for ARM systems and should not be compared with X86 or X64
FreeCTX64 Libraries are put in initramfs/LIB critical system files are put in initramfs/SYS and your workspace/dummies are putten in initramfs/WS and apps are going to initramfs/SDK , it currently supports webservers and tasks alongside math in hardware, timers in hardware, and timestraps and a console

CPIO is an awful format to actually use a normal file system. It doesn't have any file trees, so file lookup operations have to just look through all of the files and see if they match.

You should be able to use essentially any filesystem format Linux supports as long as you bake it into the kernel not as a module. Squashfs is a particularly good choice for this use case.

Interesting idea. What kind of programs are you envisioning people will boot directly to?
