Is "As a cp alternative" necessary?
GNU's Template:Codeline does preserve mode, ownership, and timestamps. It also provides the Template:Codeline option which preserves even more. I can only assume the article is talking about an older GNU cp or a cp from some other UNIX environment.
I don't know that there are any Arch users who are using something other than a recent GNU cp from Template:Package Official. I don't see how this is relevant to Arch Linux (or any other modern GNU/Linux distribution). James Eder 16:54, 30 July 2011 (EDT)
