- This is a nit, but the only version of SunOS with a pageable kernel was a
- 386i version of SunOS 4.0. I'm not sure if it was ever released, or if it
- was just experimental. SunOS on Motorola and SPARC processors does not,
- and probably never will, page any part of the kernel text.
-
- Of course, as the kernel text and locked down kernel data gets larger, you
- will see more paging and swapping of user processes.
