Currently, most parts of the build are pinned to a given version using rust-toolchain.toml and Cargo.lock files. However some parts are not, essentially things installed globally, like apt-get install.

It's not great to force a version on the user, so a solution needs to be found to localize those global tools. Building in a chroot? Not enforcing the version but only measuring it? Getting rid of those global dependencies (like #607)?

EDIT: Made obsolete by #102 and following PRs.

Possible solution for cargo install:

• Use --root=_/root to install locally. It might be a good idea to put all generated and ignored content under _ (e.g. _/target, _/root, _/node_modules, _/applet.wasm, etc) to make it easier for tool that must ignore such content.
• Use cargo search $crate | sed -n '1s/^'$crate' = "\([0-9.]*\)".*$/\1/p' to search the latest version.
• Need a solution to track the expected version (which is read by setup.sh and ci.sh and updated by upgrade.sh).
• Check current version by processing the output of cargo install --root=_/root --list.
