Well, you *might* be able to get it working with an FHS container and
maybe an overlay mount.
What I would personally do is install Arch in a chroot and install
rustup there.  You can even use Guix within the chroot if you bind mount
it.
If you want to try that, I have a more detailed how-to that I can send.
