I can personally attest (having been in the room during many of that those discussions) this is a true statement.

The early versions (certainly thru .1 - the original system called Interface), AT&T team, and a number of vendors particularly the European ones - tried hard to push the SVID to be POSIX, although many of us had used a lot of BSD in our systems fought back. Can not say it was a fun time. The problem was everyone in the room wanted to be the big dog and to have all the food -- no one could really admit that we were all in it together and the real competition was elsewhere.

FWIW: Keith Bostic occasionally came to some of those meetings from CSRG to some of those meetings and was amazingly gracious/patient. It's why 4.4 had a number of things in that made it closer to POSIX.
