If I'm right this should fix #2579

@jyn514 Is this what you were expecting / desiring? If so, you can look at the built artifacts and fetch a test rustup to try.

Just a tiny nit. Thanks so much for adding this!

How can I look at the built artifacts? Found it, it was in the GitHub actions screen. I had to be logged in to download the artifact for some reason.

Tested it out and it works great, just like I'd expect :)

I've worked through the code suggestions and if this goes green I'll merge.
