In any case, what I am trying to do does not disqualify build-id 

I understand that part but I find disappointing a feature designed
specifically for this purpose and already deployed for 5+ years is being IIUC
ignored.


(I'll use it in fact, if present).

I do not see how you verify the NT_GNU_BUILD_ID content.

No, it's not done now in the current patch. I meant the new patch will.



Note also that I really want a solution that does *not* rely on
section headers but rather only on load-time required stuff.


build-id specifically does not depend on any link-time data (sections) to be
usable for runtime core generations.  It is (also) available from program
header PT_NOTE as NT_GNU_BUILD_ID.

That is great, thanks.
