    # rustup is installed by the root user in a non-default location
    # /usr/local/rustup, so $RUSTUP_HOME is required to access rust config
    # e.g. default toolchains and run cargo
    #
    # leave $CARGO_HOME blank so when this is run by the buildslave user it uses
    # the default /home/buildslave/.cargo directory which it has write
    # permissions for - that allows it to download new crates during compilation
    #
    # since rust was installed by root, buildslave user does not have write
    # access to /usr/local/cargo and will error when trying to download new
    # crates otherwise
    #
    # note: $PATH still contains /usr/local/cargo/bin at this point so cargo is
    # still run via the root installation
    #
