- Hi
- Is it not true that the actual kernel is itself freely-distributable but
- to be of any use, you need the BSD server and unix emulator which
- provide
- the necessary file system and system call interfaces which unix programs
- expect. On its own the Mach 3.0 kernel is nothing more than a
- micro-kernel with no file system or concept of a user interface.
- I believe that these parts are non-free, ie. you gotta pay $$$ for them!
- This I surmise from the following message from CMU (Mary Thompson):
- "
- Subject: Research Distribution of Mach 3.0
- Author: Mary R. Thompson
- Date: Feb, 1992
-
- We are distributing the pure kernel with or without
- the single server Unix environment to outside research groups.
- Note that we are not providing a complete operating system and this
- should not be thought of as an upgrade from Mach 2.5 or 2.6 MSD.
- [ stuff deleted ]
-
- Access to the Unix server requires Berkeley licensing as in Mach 2.5, but
- access to the kernel itself, Mach libraries, etc. does not.
-
- [stuff deleted]
-
- The initial distribution consists of sources only for the kernel, Unix
- server and some Mach programs. The Unix server provides only the
- functionality of the Unix kernel. Neither the sources nor binaries are
- supplied for the complete Unix operating environment.
-
- [etc]

- See what I mean?
