Hm, something missing from that sentence, eg. "variant in the same dir"?

Actually, if I understand correctly, that's not a benefit, it's
breakage.  The debuginfo packages would then contain the symbols and
sources primarily for the last variant built in the loop plus possible
leftovers from earlier builds, with probably most of the earlier builds'
stuff overwritten or removed.

Both the contents of the sources and symbols may and do differ between
variants, and it's possible for some variants to contain modules and
sources not at all present for others (which should be obviously
avoided).  The lirc package is an example of all this.

+1

Here's a couple of updated example packages, converted to use kmodhelper
(I suggest /usr/lib/rpm/redhat/kmodtool and %{kmodtool} for it, BTW) and
avoiding debuginfo problems.  Also added some additional known variants
to the script.  The code in both packages is in a pretty bad shape
regarding the latest Rawhide kernels (most modules disabled in lirc,
thinkpad doesn't compile at all), but better on FC4, and anyway good
enough for illustration purposes.
