- RISC iX is and always has been based on BSD 4.3, i.e. the latest full
- release of (AT&T-derived) BSD UNIX from Berkeley, in conjunction with
- Sun NFS code and various other stuff. BSD 4.3 is best described as a
- "solidified" (i.e. more reliable and better tuned) version of 4.2:
- there isn't that much difference between them anyway.
-
- Perhaps Gary might care to re-consider his opinion. After all, it
- seems somewhat unreasonable to expect that a product which was in
- development for around two years before its original launch 3 years
- ago (and which has been substantially developed since then), should be
- based on a source tape which may or may not (have) come out this year!
- The point is, switching the version of BSD you choose to base a
- released product on is no trivial matter, especially when the changes
- to the internal structure are so substantial as they are between 4.3
- and 4.4.
