Yes, a 'NIX users group.

No, I didn't say anything like that.

Because they are highly qualified. One is a professor of computer sciences
and runs the University BSD servers. with the help of his more advanced
students to give them a little cash in hand to keep them from starving to
death and give them real world experience.

I can't, for the life of me, see any other party referred to in that
paragraph.

Yes, it will be.

Up until halfway through the 2,4 kernel, that's how it was done. If you
wanted ext3, for example, it was as a module, because only ext2 was compiled
in.

Ellison's not about to let anything go, because that's the way Ellison is.
The CDDL will stay as it is. It is compatible with the BSD licence however,
which is why it can be employed with Debian's KFreeBSD config., for example.

There's nothing wrong with loading it as a module. Debian isn't exactly in
the Microsoft patent heavy market scenario, but still supplies access to
contrib and non-free apps. What's so different here?

I didn't say it was here.
I seem to have stated that Linux have an over abundance of them.
