https://github.com/servo/servo/pull/19395 has (finally) landed. Instead
of custom scripts, Servo now uses rustup.rs (which needs to be installed
separately) to download and manage various versions of Rust and Cargo.
These files are kept under $RUSTUP_HOME/toolchains. $RUSTUP_HOME
defaults to ~/.rustup
If you’ve built Servo before yesterday, you probably have a .servo
directory under your clone of the servo repository that’s taking up disk
space with previous copies of Rust and Cargo. It can now be removed.
Similarly, in the default config we used to override $CARGO_HOME (which
contains a cache of crates.io and git dependencies) to .cargo under the
repo. You also remove that, now we leave the environment’s $CARGO_HOME
(which defaults to ~/.cargo). This cache is now shared with other clones
of the repository, or with other projects that might use some of the
same Rust dependencies.
