Ubuntu 25.10 will replace the sudo command with sudo-rs, a new Rust rewrite designed to improve memory safety and security. What does this mean for users?
Sudo uses the setuid bit or whatever, so it still has access to the user’s environment variables and whatnot. So figuring out which editor to run shouldn’t be an issue.
That’s not what I mean. Yeah, getting the environment variables are simple enough, but if you simply exec something as the root user, whatever you exec will naturally be looking for configs in /root/.config and not your~/.config dir, so any configurations to things like your text editor won’t be read.
