Well, calling system with a list as parameters isn't necessarely 'safer'. It means that the shell is bypassed. Since you don't know what's inside $node, you don't know whether it matters or not. Perhaps $node contains whitespace, or backticks, or dollar signs, making it vital that the shell plays it part.

Don't suggest alternatives without pointing out what may break.
