OK, if you feel that way I'm attaching the requested details below. I
hope that this thread doesn't stall into some implementation detail
issues.

It's rather trivial and really doesn't deserve the attention it
receives, but at least I hope that it makes clear that all
implementation details have been carefully thought of already or
matured in the last three years.

So, do you buy it now? :)

No, remember that the kmdl scheme is a clean and KISS interface/
implementation design. Furthermore debuginfos are hidden as an
implementation detail in conventional packages, too. So starting to
add such information to the specfile or the kmdl interface part would
be wrong or a hack. It belongs to the implementation part, aka macro
definitions.

Surely is my middle name, but I prefer Axel ;)

In fact renaming after the fact would be dirty and would leave traces
in the resulting debuginfo package (the internal rpm name would still
be the one before renaming). I prefer modding the macros. It's a
simple change, but since I don't want to touch the upstream macros
(well, I do want to, but rather in the source itself ;), I override
the macro with a local copy. No, let's not get distracted about what I
have in mind about future redhat-rpm-config contents ...

In order to avoid any further inquiries on this rather trivial issue I
even diffed the original macro to the one I use to reveal all the
magic at once (note again: the macro is overridden, not replaced in
the original definition, this is a convenience diff).

%kmdl_userland is always 1 unless the package to be built is a kernel
specific kernel module (the default for %kmdl_userland is an
implementation detail, for FE's buildsystem it would probably be the
other way around). So project foo ends up with debuginfos naturally
named as

foo-debuginfo-1.2.3
foo-kmdl-2.6.20-4.5.6-debuginfo-1.2.3
foo-kmdl-2.6.20-4.5.6smp-debuginfo-1.2.3
foo-kmdl-2.6.20-4.5.6PAE-debuginfo-1.2.3
[...]
