Something like that doesn't seem unreasonable, so the classes/recipes don't
have to worry about the particulars of the recursive copy tool being used.

That said, doesn't cp -r result in correct ownership, since the files are
created without preserving permissions or ownership? I'm pretty sure it's
the cp -a / cp -pPr that we need to be more concerned with.

Note that with gnu cp, it's possible to tell it to preserve permissions,
but not ownership. It's not portable to non-gnu cp, but I don't know what
we care about that anyway.

Ex.: `cp -a --no-preserve=ownership`
