Yeah, I think Posix started with SVID (the System V Interface Definition from AT&T), then cleaned things up and standardized some extensions. Then again, BSD tries to follow Posix, at least to some degree. I'm not sure how much of the system admin stuff is specified by Posix, but that's where the differences between SysV and BSD are most apparent to me.
