- By this statement I was trying to imply that it was only the microkernel
- part of the Mach 2.5 distribution that was used and not the Unix part
- (although for the pedants, I'm sure a line or two slipped in). In fact the
- Mach 3.0 kernel was based on the 2.5 "microkernel" and only the IPC interfaces
- changed significantly (although again I'm sure other changes have been
- made, sigh, the things you have to do to protect against flames)

- Well, I did say *simplistically*. In fact OSF and Berkeley worked closely
- sharing what was to become 4.3 Reno and will become 4.4. Bugs found and
- fixed at OSF will be in 4.4 and vice versa.
-
- If you had wanted a technically precise and accurate description then
- you can always attend the OSF/1 internals course.
