- Some quick back-pedaling is in order here:
-
- I have been informed that I'm also a bit off. Apparently NeXTOS is built
- atop a particular revision of Mach (2.[23]) and is not really a micro-kernel
- OS.
-
- At least in this regard, it is very similar to SunOS. (Thank goodness it's
- not similar in some other aspects ;-)
-
- I took my (limited) knowledge about what Mach claims to be and the fact that
- NeXTOS is built upon Mach - the unfortunate discrepancy in Mach's history
- caused the problem.
-
- Now, I didn't claim to be an OS/kernel guru, so I can get away with this
- mistake, right? ;-)
