The reason it's that way is because I hate with a bitter and
incandescent passion the kind of HOWTO that baldly lays out a series
of steps without also teaching the background needed to troubleshoot
when a step does not lead to the expected result.
Such HOWTOs leave the reader totally at sea in case of failure, and
tend to age rapidly and badly. I will never write one like this.
The only way I know to prevent this failure mode is to write in a way
that conveys both instructions and *expertise* - teaches not just what
the steps are but *why* they are, in effect pulling the reader partway
inside the mind of the author.

Easily enough accomplished with :toc: in the options block. I think this
is a good idea, and have already made the change.

Branching that way would fight with one of the document's design
goals, which is to walk the reader through the build with rich context
- the "why it's this way" and the "what do I do if this fails?" - at

I don't consider this a simplification just because it has a GUI. It's almost
certainly not going to have the intelligence about defaults that ddimage does.
In what sense do you think it is better, exactly?

That "dovetailing" idea bothers me. The narrative sequence is an important
tactic for conveying the meaning of the steps. I will be very reluctant to
trade it for any organization that is formally prettier but not as good at
educating the reader. You'll have to convince me about that.

Well, not if you're OK with scattering multiple modifications on the same file
across different steps the procedure. That may be justified in this case, but
it;s not yet obvious that it is.

Yeah, there's a better case for that.

Offer accepted. :-)
