Rust provides a uniform way to install on any Unix you say? Compared to polyglot boarding house which is Linux package management?

rustup is also installable via your package manager, but, if it isn't, that's kinda your own distro's problem. The problem is that Linux is non-uniform. The problem is not Rust for providing a uniform, lowest common denominator, method for Unix. Notice Windows doesn't have the same problem.

Compiled?

Please explain the material security differences between the use of rustup.rs method vs. using a package manager.

I'll wait.
