Do you have SCCS files from the time between 1987 and 1990? I have a SVR3 AT&T source from 1986 and a S5R4V1 source from January 1992. This allos to verify, that the SVR4 kernel is _very_ close to the SunOS-4.0 kernel and very far from the S5r3 source. Even the S5R4V1 source did not include any of the new features in e.g. the UFS implementation, such as "clean flag" and I/O clustering. Also S5R4 neither comes with "lofs" nor with "hsfs". Later S5R4 versions added "cdfs" as a "hsfs" replacement.
