cd zCore
git lfs pull

Prepare Alpine Linux rootfs:

make rootfs

Run native Linux program (Busybox):

cargo run --release -p linux-loader /bin/busybox [args]

Run native Zircon program (shell):

cargo run --release -p zircon-loader prebuilt/zircon

Run Zircon on bare-metal (zCore):

cd zCore && make run mode=release [graphic=on] [accel=1]

To debug, set RUST_LOG environment variable to one of error, warn, info, debug, trace.
