I really don't understand why Canonical rushes this. If 'rm' can't remove all possible directory entries, that is a big issue: $ podman run --rm -it ubuntu:26.10 $ apt update -y; apt upgrade -y $ rm --version rm (uutils coreutils) 0.10.0 $ gnumkdir -p $(yes a/ | head -n $((32 * 1024)) | tr -d '\n') $ rm -rf a Segmentation fault (core dumped) rm -rf a $ ls a a $ gnurm -rf a $ ls a ls: cannot access 'a': No such file or directory

From the company that distributed Amazon spyware ( https://www.fsf.org/blogs/rms/ubuntu-spyware-what-to-do ) and now turns Debian into Slopian. No thanks.

You can use coreutils-from-gnu instead uutils. However since 26.04 build-essential depends on coreutils-from-uutils, it cannot be upgraded while coreutils-from-gnu is installed. https://bugs.launchpad.net/ubuntu/+source/build-essential/+b...

Was there something wrong with how they are currently written or do they just want the badge that says they converted to Rust?

Has the code quality in that repo gotten to a good point then? I haven't followed it much, but last I looked[1] (which was a few years ago) almost every tool I looked at in detail had pretty bad performance or correctness issues. [1] https://jackson.dev/post/rust-coreutils-dd/

Hmm, this doesn’t make sense. You simply don’t replace utilities with many decades of maturity and that “just work” with something that is not as mature. It will open all users of the distro to all sorts of subtle and not so subtle bugs. I for one don’t want to find myself staring at a mysterious segfault when I want to build the latest version of nodejs or flash a microcontroller. It’s such a pity; I have used Ubuntu for close to 23 years.

Everything online reminds of when Ubuntu switched to dash for init scripts or something. Good times.

So what is the way forward for Linux to have sandboxi g as strong as Android? Appimage everything? I know it's possible now hacking together things, but I mean by default and integrated.
