It's incomplete and just plain wrong is so many places." The whole tar/cpio stuff from /usr/group was a great example of the start of it, but even things like trying to define a directory entry was strained. SVID did not have the new UCB directory system calls. For example, we all were certain that if we ever had a different FS, we needed to remove physical formats from the specification. There were no sockets, and yet nearly 100% of the working networking code in the wild, including on MS-DOS, was using sockets. </span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">The problem was that several people who came to the POSIX meetings post-SVID from AT&T were from marketing and sales. At the same time, the core of the original /usr/group and later POSIX teams were mostly engineering types. The sales/mktg folks were trying to establish a brand, the engineers were trying to solve an issue were we had code that did not work between our different systems.</span></div></div></div><div hspace="streak-pt-mark" style="max-height:1px"><img alt="" style="width:0px;max-height:0px;overflow:hidden" src="https://mailfoogae.appspot.com/t?sender=aY2xlbWNAY2NjLmNvbQ%3D%3D&type=zerocontent&guid=be6cf864-5389-482c-bc7c-6a6878463a2a"><font color="#ffffff" size="1">ᐧ</font></div>
