I just found out that I can ovverride the line

hostname = "${MACHINE}"

hostname_pn-base-files

Now I wonder where this kind of black magic is documented, I don't
seem to be able to locate any document that explains the "_pn-" syntax
and I wonder if there are even more such tricks that could be useful
and am looking for a document that explains them all. Is there such a
thing?

Yes, of course. This:

and this:
