This makes sense too. I was thinking it'd be easier if we could grab
everything that we needed from a single CVS. I'm not expecing a lot of
changes either. The only one I can think of offhand is a patch to allow
fiasco to boot with more that 128MB of memory installed.

I'm between jobs right now, so I have time to work on this. This would
depend on how easy it would be to convince the Hurd people to allow
write access to their CVS for this project. I'm more interested in
generating some progress. It'll be easier to get access once we have
something to show. At the moment, it's just a lot of bright ideas. We
need some code.

Convenience, write access, and a record of our changes are again my
thinking here. We also can't code against a moving target. It seems to
me that it would be easier to have our own version to work with so that
we could merge their progress into our stuff as things progress. That
way we are feeding patches in both directions, and we don't have to feed
the real Hurd anything until we have it at a point where it is good
enough to do so.

I agree that we should work with both kernels. Everyone seems to be
saying hazelnut to start, so I think it's decided. Hazelnut it is.

I guess not. It's a part of the fiasco CVS right now. I don't know what
the interdependencies are. Since we are using Hazelnut, I guess it isn't
important at the moment.
