Yes, I agree. I did not mean to imply that literally any other language would have been better for sudo, which I see is a viable reading of my original post. Go, for instance, would be a terrible choice, because the way the runtime deeply assumes you're running in a multithread environment, even before it gets to your "main" function, means that exactly the sort of UNIX hackery sudo is designed to do is effectively impossible. I have a system myself that is otherwise entirely in Go, but we have a very small C-based wrapper whose job it is to be setuid, open a few files with the escalated privileges, do some user verification, then change its uid and gid and exec the "real" Go program, because Go just can't do those things.

Dynamically typed languages as a whole would be a bad idea.

Java's startup time for such a small executable would be a problem.

I'm just saying this problem is unique to C, and in my opinion, sufficiently endemic to security software to disqualify it entirely.

Mind you, you might well end up at Rust in the end anyhow. Perhaps D. It isn't necessarily a long list for a sudo replacement. But...

C delenda est.
