Alternative installation methods removed

User:grawlinson did a "major refactor" with [1] and part of the information hasn't been added back to the article. Specifically archlinux-nixAUR, which uses upstream binaries, is no longer mentioned.

The manual installation was removed in a previous edit with [2]; however, pages like Rust still mention installation through curl (albeit with a notice to actually check what has been retrieved before executing it).

This already caused complaints on IRC because nix was reported as non-working, and other methods are now undocumented. -- Alad (talk) 12:20, 1 July 2021 (UTC)

Acknowledged. I'll revert my changes. Grawlinson (talk) 23:43, 1 July 2021 (UTC)
