Nowadays cp -a works well everywhere (in my experience) so there's no need to resort to tar. It's just damage from the Unix wars.

BSDs included? In my experience they've been mighty picky about the GNUisms (or "things that would have been GNUisms if someone else hadn't done them first") they're willing to implement.
