        I have a plan for something like this, though currently there is
 no code. I was thinking of doing an "overlay" for ./debian, kind of
 like what ikiwiki and request-tracker do; so /usr/share/kernel-package
 contain the information that goes into ./debian; but if there is a user
 specified overlay, then files present in the overlay are used instead
 (files not in the overlay dir still come from the default location).

        I have not yet written the code, since there are several places
 in the build where we look for files in ./debian; and currently there
 is a fallback to /usr/share/kernel-package if ./debian does not exist;
 either I have to remove the fallback, or enhance the fallback mechanism
 (at potentially significant run-time cost).

        The cleaner solution would be for make-kpkg to always remove and
 re-create ./debian (with overlays), but make -f ./debian/rules never
 have to deal with anything outside (so to remove the fallback code that
 has sprouted all over the rules files). It might take a few iterations
 to do these changes, but I think it is worth it, for robstness' sake if
 nothing else.

        Please. I have been thinking about the request you made for
 debugging symbols being packaged, and now I do have some time to play
 with building kernels again, I would like to see that in Squeeze.
