Indeed, it is needed and it exists - Raspbian
is Debian for the RPi is the saying (and it is
true).

Yes, but not the actual source Emacs was
compiled from, right? (But the difference is
perhaps academic.)

Why don't you put this together and suggest it
as an addition to (info "(emacs) Checklist")

Actually I think there should be a
"How to use GDB when Emacs crashes" node
(child/leaf) from (info "(emacs) Bugs") .

"Checklist" is like a typical thing people
typically don't like to check out! You get the
feeling there is a schoolteacher behind that
door telling you to improve your handwriting,
or something.
