I have this Dockerfile which builds my Neovim setup inside an Arch Linux container. Following logs show the amount of space each layer takes. The command rustup install nightly took 1.05GB of space which sounds unusual to me. Is there any way to reduce the amount of space taken my Rust nightly?

rustup install --profile=minimal nightly reduce the space by almost half. I can see, minimal has no docs included.
