While your points are good and valid, I'd like to point out there is is a good reason to invoke cp via system instead of using File::Copy: The latter doesn't preserve file permissions on Unix and Linux.

(Actually that's pretty sad for such an old piece of software. There's been a thread about that on p5p during the last few months, but I don't recall what the result was, if any.)
