This is what upstream Gentoo does. They would previously update the entire seed, but this took a long time. Our seeds are much bigger, so we kept repo snapshots to build stage1 against these instead. The new method of only rebuilding packages with changed sub-slots is a good compromise and removes the need to write stage1 hooks that selectively catch the repository up. This also avoids some conflicts by adding the `--ignore-world` option. Gentoo seeds have nothing in @world. We have much more, but none of that is needed for stage1. This continues to exclude cross-*-cros-linux-gnu/* as that is not needed for stage1. It now also excludes dev-lang/rust, because it is never a DEPEND, so it would not break other packages in this way. It may fail to run due to a sub-slot change in one of its own dependencies, but it is also unlikely to be needed in stage1 and it is not configured to use the system LLVM. If needs be, we could improve the behaviour of Portage's @changed-subslot to respect `--with-bdeps`. In my testing, it was unable to handle an SDK from 17 months ago, but one from 7 months ago did work. In practise, we will always use a much more recent one, which is far more likely to work.
