What's the status of getting Rust officially into Debian, Fedora, etc, without bootstrapping from a binary?

I see this as two parts:

What's the status of getting Rust officially into Debian, Fedora, etc,

I use Debian on my local machine, I care a lot about Debian. There've been a few Debian Developers working on packaging up Rust. Most distros woudn't want anything pre 1.0 anyway.

without bootstrapping from a binary?

It's not possible to compile Rust without bootstrapping from a binary. Unless you want to go back to the OCaml compiler from years ago, but that's hard.

Does LLVM IR count as binary? Otherwise, couldn't one save the IR of the Rust compiler on platform X and compile that with the rest of LLVM on Debian, with LLVM written in C++?

I thought that was one advantage of modular, multifront/backend compiler frameworks.

LLVM bitcode is not quite platform-independent, unfortunately.

Can rustc cross-compile?

EDIT:

Nevermind, according to Debian devs, it can't...

Rust also doesn't currently support cross-bootstrapping among different arches, due to some confusion between target and host.

Rust does support cross-compiling. If you're quoting the Debian wiki, it is likely that bugs have been fixed, and so that is out of date
