IMHO, Rust is not that difficult to learn but it is difficult to
run.

One point of difficulty for me still is the QA part, not really the
code. QuickStart discusses on how to install all the shenanigans
with distribution package managers.

The reality of actual kernel development is that you almost never
compile/run host-to-host, rendering that part of the documentation
in the battlefield next to useless.

Instead it should have instructions for BuildRoot, Yocto and
perhaps NixOS (via podman). It should really explain this instead
of dnf/apt-get etc.
