--- Comment #9 from Andrew Macleod <amacleod at redhat dot com> --- sooooo. Include them all with an accumulator file as suggested? Over a run of multiple generations you have to expect some sort of flux in include structure, especially since we don't guarantee much. The only way I see you can have any kind of stability is to have a standard file you include which can adjust and include whatever is needed for any given release.
