Reading that Canonical thread was jaw-dropping. Paraphrased: "Rust is more secure, security is our priority, therefore deploying this full-rewrite of core utils is an emergency. If things break that's fine, we'll fix it :)".

I would not want to run any code on my machines made by people who think like this. And I'm pro-Rust. Rust is only "more secure" all else being equal. But all else is not equal.

A rewrite necessarily has orders of magnitude more bugs and vulnerabilities than a decades-old well-maintained codebase, so the security argument was only valid for a long-term transition, not a rushed one. And the people downplaying user impact post-rollout, arguing that "this is how we'll surface bugs", and "the old coreutils didn't have proper test cases anyway" are so irresponsible. Users are not lab rats. Maintainers have a moral responsibility to not harm users' systems' reliability (I know that's a minority opinion these days). Their reasoning was flawed, and their values were wrong.

Agree with the point. Asking sincerely, how to filter out installing any rust-rewrite packages on my machines? Does anyone know the way?
