Perhaps I was mistaken about your needs, in that case, as I at first
thought derivatives mode was what you were after, since you appeared to
be one. I did not understand at that point that it was not really
suitable in the case where your derivatives model is not live-build's
derivatives model (which is Debian as a main repo *plus* the
derivative's extra repos, rather than the derivative wholly replacing
the repo, which is supported with --mode as in Ubuntu's case).

Daniel did not tell you to use derivatives mode. He said *if* you use
derivatives mode, use a26 or newer. I believe I was the first to point
out that 3.x has a derivatives and wondered if that would be a good fit
for you.

The man page of which version? In a26 and a29 there is:
--mirror-chroot URL
sets the location of the debian package mirror that will be used
to fetch the packages of the derivative in order to build the live
system. By default, this is set to the value of --mirror-bootstrap.
Seems clear to me.

Please check which version you got that excerpt from.

Historically, --mode changed the major mode of operation for numerous
things for a project such as ubuntu or emdebian that does not adhere to
the Debian repo + additional repository model. Supporting such
derivatives had quite a bit of extra overhead to handle each case, as
such derivatives diverge so much from Debian that we cannot know exactly
what they contain. Therefore, it has always been necessary that at least
one person who both knows their own derivative intimately and knows
live-build code intimately provides us with a stream of patches to
continue to support their mode to keep up support for it. As you can
see, that's not an easily sustainable model.
As I understand it, the new support is for a lighter weight alternative
model for derivatives, having most packages taken from Debian and
additional packages from the derivatives repo. This "Debian plus" model
of a derivative is much easier to support because it is essentially
Debian with few changes to packages concentrated in the additional
packages that derivative provides.
Your model seems to be something that is not quite one and not quite the
other. You're not a "full derivative" (for lack of a better term) which
completely branches from Debian, replicating all our infrastructure
(including people within your project who intimately know live-build and
provide us with patches). Nor are you a "Debian plus" derivative, which
would be a lot easier to support.

Clearly it doesn't need "a few words", as no amount of words so far have
led us to a satisfactory solution, especially since we're not even
consulting the same versions of the man page.
I haven't the time before I head out to work to address each additional
point of your email point by point, but until we're at least discussing
the same man page version, I am not sure what the point of it would be.
