rlos

An experimental minimal Linux boot chain - a step toward rl-lang's long-arc goal of building an OS userspace in rl-lang.

Currently: custom-built kernel + a minimal initramfs booting into a shell. Init is C for now; userspace binaries include rl running inside the environment. rl-lang's own coreutils/shell (rlsh, core-utils) are the intended long-term replacement for busybox.

• Kernel builds and boots in QEMU
• Minimal initramfs (mount proc/sys/dev, console setup, exec into a shell)
• busybox as interim shell
• rl binary runs inside the environment
• rl-lang shell (rlsh) as PID 1's shell, replacing busybox
• Init rewritten in rl-lang

Clone and build the kernel, using the config in this repo:

./compile_kernel.sh

./compile_init.sh

Compiles init.c.

./build_rootfs.sh

./compile_initramfs.sh

./run_qemu.sh
