All the scripts in mnt are from the Technical Reference Manual
You do not need to install any packages when running the container, it's all included in the build.
The directory mnt is bind-mounted to the container /mnt
When you run the scripts, the contents of the git pull and build etc will e in the mnt directory.

Enter the build environment with a command prompt with: ./shell.sh

Build scripts available:
build_kernel.sh build_opensbi.sh build_spl.sh build_u-boot.sh
These scripts just removes the directory before fetching it from git, so be aware any local changes in those will be wiped.

Quick build of everything:
./shell.sh build_all.sh

or manually for each step, making changes along the way.

u-boot: ./shell.sh build_u-boot.sh

OpenSBI: ./shell.sh build_opensbi.sh

SPL and payload: ./shell.sh build_spl.sh

Linux kernel: ./shell.sh build_kernel.sh

Alternatively, linux kernel based on a-wai/vf2-linux, this enables IPv6 and docker: ./shell.sh build_kernel_vf2.sh This also builds modules and installs them in mnt/lib/modules.

Build the rootfs with: ./shell.sh build_rootfs.sh

If you want to test run it, make sure you have the proper qemu installed docker run --privileged --rm tonistiigi/binfmt:riscv
First build the image with ./rootfs_image.sh and then start a container shell with ./rootfs_shell.sh

If you're using podman, simply replace the above build.sh with podman_build.sh and shell.sh with podman_shell.sh
