I know this isn't your point but this is exactly why I don't use docker--but I'm a bit surprised to hear you mention `cargo build` as something that might fill up the disk. I've been a vocal critic of Rust on Hacker News in the past, but the one thing I always thought they did very, very well, was Cargo and the tight executables it produced for me.
