Yes, there was some version of the Posix standard in that time frame. 
It was just incomplete and described some mythical system that matched 
no existing BSD or SysV flavor, so it was mostly ignored.  Sort of like 
the previous and current Linux FHS versions that just move things around 
arbitrarily without sufficiently describing a portable runtime 
environment for an application.
