I guess that we could also read the src/ci/channel file? But this seems good enough.

AFAIK we could (that's the initial approach considered), but the logic above doesn't read that file either, and instead derives it from the archive name of the dist artifact, which is why I wrote this hack instead...

FTR, this is what I meant by #134528 (comment), should've clarified.


// Extract rustc, libstd, cargo and src archives to create the optimized sysroot
let rustc_dir = extract_dist_dir(&format!("rustc-{version}-{host_triple}"))?.join("rustc");
let libstd_dir = extract_dist_dir(&format!("rust-std-{version}-{host_triple}"))?

The dist version extraction above this is slightly hacky, and so is this, but oh well.

"nightly" => "nightly",
