The information about the nameservers, the tftp server, and the ntp
server, is supposed to refer to infrastructure that already exists.
I think your test hosts should be in the DNS, yes.  It may be possible
to get it to work without doing that but I wouldn't recommend it.

osstest does not need a dedicated network.  Specifically, it can
share its broadcast domain, and its dhcp and tftp servers (and web
proxies, Debian mirrors, ntp servers, and so on), with other uses.

When running osstest in production ("Executive") mode the individual
test boxes must be configured to be available to osstest only if they
are not being used for something else, of course.

See INSTALL.production.

See under DHCP in INSTALL.production, and please let me know if that's
not clear.

mg-debian-installer-update downloads d-i installation information and
puts it in the tftp area.

But the tftp area is also updated at runtime, obviously, in order to
control the booting of each host.  And the mirror host is accessed
separately, too.

I'm happy to answer more questions, of course :-).

That blog post may be rather out of date, I'm afraid.  But the in-tree
documentation is somewhat better since then.

I'm not familiar with the referent of "moonshot" in this context.  IME
"moonshot" is a project name chosen multiple times, for different
projects, by people who want to give an impression that the project is
ambitious.
