[coyotos-dev] About coyotos tutorial

[Jonathan S. Shapiro]

Mr. Lin:

Thanks for your interest, and thanks for asking.

You are right. The current tutorial/ directory is a place-holder. We
added it when we were preparing to do a tutorial for a client. but then
we decided together that the tutorial should wait until we could run
real code.

We are now very close to that, and we expect to do a tutorial for the
client in July. You can expect some activity in the tutorial/ tree
around mid-July.

CapROS has the advantage that they are building incrementally on the
older, working system. Coyotos is a completely new implementation.
Charlie chose to clean up and increment. We chose to re-build a clean
implementation.

I will get instructions written for how we do this.

I don't want to discourage you, but I think that re-working the
tutorials is not a good use of your time. Coyotos kernel does not really
run yet, but it will be running in another few weeks.
