Rustup won't install rust-src src files on nightly 1.48

Problem

Rustup won't install rust-src src files. Library and Cargo.lock are present. But no src folder.
Steps

1. install rustup 1.22.1
2. install nightly toolchain
3. install rust-src component to that toolchain
4. the src file is missing from ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust

Notes
This is not present on stable toolchain
Output of rustup --version: 1.22.1 (2020-07-08)
Output of rustup show: rustc 1.48.0-nightly (0da580074 2020-09-22)

This is expected, the rust-src component only includes the standard library. Is there something specific you are looking for? The rustc-dev component recently added the compiler source.

My bad then. Probably out of date instructions on rust-analyzer side
