Christian's Operating System

Includes the kernel and userspace libraries/applications.

Building

make -C kernel
cd build
sh build-initrd.sh
sh build-limine.sh

Run make in the /kernel directory. This should produce the file kernel/dist/vmkernel, which can be run by any Stivale2-compliant bootloader. Run sh build-initrd in /build to generate an initrd.img to pass to the bootloader.
