The coreutils Rust rewrite story is pretty funny.

Coreutils are tools like rm, mv, mkdir, etc. Unlike binutils, this isn't a fertile ground for memory safety bugs. But, the rewrite was completed, and in the spirit of progress, Canonical decided to switch.

But do you know what coreutils are a fertile ground for? Race conditions around file creation, deletion, permission setting, and so on. The original code accounted for decades of hard-learned lessons in that space. The Rust rewrite did not:

PS. I'm not dunking on Rust. It's just that... starting over from scratch has its hidden costs.

@lcamtuf Rustaceans are the problem, not Rust itself. theyre like a lobbing group trying explicitly to boost their future employment demand much more than prioritized on doing the right thing as engineers or for the community. much like the AI VC are "talking up their book" even if its poison for the rest of us

@synlogic4242 Uutils started as someone’s personal project to learn rust, and “write a system utility” is frequently used as a basic exercise for learning. Uutils is doing exactly what it set out to do.

It’s not the fault of uutils that Canonical is dumb.

@rmq @lcamtuf I view it as both their fault. I'm pissed that after having to deal with Copy.Fail I now have to wipe other people's butts again for them. and I worry this will happen with more frequency as more vibe-coded software spreads around

@synlogic4242 @rmq @lcamtuf Do you have any concrete pointers or sources for uutils actually contributing to the problem, since it seems pretty well established that this has been solely Canonicals choice, or are you just dragging in rustaceans because you feel like it?
