[Fedora-packaging] file-conflicts on updates problem

Hi all!
I was looking at the current kmod situation a bit again and tested some
stuff and it seems I'm to dump to reproduce the "file-conflicts on
updates problem" -- a problem that I saw myself some weeks ago once IIRC
and that was multiple times brought into the current discussions by Axel.
Seems I'm doing something wrong here. Can somebody tell me that that is?
I uploaded two srpms for testing to
http://www.leemhuis.info/files/fedorarpms/MISC.fdr/kmod/
for people to reproduce the problem locally. That's not a real kmod, but
it uses the kmod-scheme and a "kernel module" for testing which is
created by
> dd if=/dev/urandom bs=1k count=500 > $RPM_BUILD_ROOT/lib/modules/%{kverrel}${kvariant}/extra/%{kmod_name}/foo.ko
Look closer yourself below to understand my confusion. Note, all the yum
calls are on FC5 with latest updates, but without the kmod plugin:
Prepare the test rpms:
> [thl at notebook ~]$ rpmbuild -ba rpmbuild/SPECS/foo-kmod-common.spec
> [thl at notebook ~]$ rpmbuild -ba rpmbuild/SPECS/foo-kmod.spec --define 'kversion 2.6.17-1.2157_FC5' --define 'kvariants ""' --define 'thisrelease 1' --target i686
> [thl at notebook ~]$ rpmbuild -ba rpmbuild/SPECS/foo-kmod.spec --define 'kversion 2.6.17-1.2174_FC5' --define 'kvariants ""' --define 'thisrelease 1' --target i686
> [thl at notebook ~]$ rpmbuild -ba rpmbuild/SPECS/foo-kmod.spec --define 'kversion 2.6.17-1.2174_FC5' --define 'kvariants ""' --define 'thisrelease 2' --target i686
[...]
Put them in a testrepo:
> [thl at notebook ~]$ mkdir -p ~/tmp/testrepo
> [thl at notebook ~]$ cp rpmbuild/RPMS/noarch/foo-kmod-common-1.1-1.noarch.rpm rpmbuild/RPMS/i686/kmod-foo-1.1-1.2.6.17_1.2157_FC5.i686.rpm ~/tmp/testrepo/

Copy the second one in the repo and update:

Works as expected so far. But now:

Okay, why did that work? I don't know for real. Let's check some details:
> [thl at notebook ~]$ rpm -qa kmod-foo
> kmod-foo-1.1-2.2.6.17_1.2174_FC5
> kmod-foo-1.1-1.2.6.17_1.2174_FC5
> [thl at notebook ~]$ rpm -V kmod-foo-1.1-1.2.6.17_1.2174_FC5
> ..5....T /lib/modules/2.6.17-1.2174_FC5/extra/foo/foo.ko
> [thl at notebook ~]$ rpm -V kmod-foo-1.1-2.2.6.17_1.2174_FC5
> [thl at notebook ~]$
Well, I'd call that "interesting". Seem the "file-conflicts on updates
problem" doesn't exist.
But while testing it I noticed something else. You probably noticed that
in above transaction kmod-foo.i686 0:1.1-1.2.6.17_1.2157_FC5 got removed
-- it seems that's not a rpm/yum feature. It's the installonly-plugin
that does this. Let's get back to the state we were before:
> [thl at notebook ~]$ sudo rpm -ivh /home/thl/tmp/testrepo/kmod-foo-1.1-1.2.6.17_1.2157_FC5.i686.rpm --oldpackage
> Preparing... ########################################### [100%]
> 1:kmod-foo ########################################### [100%]
> WARNING: Module /lib/modules/2.6.17-1.2157_FC5/extra/foo/foo.ko is not an elf object
> [thl at notebook ~]$ sudo rpm -e kmod-foo-1.1-1.2.6.17_1.2174_FC5 kmod-foo-1.1-2.2.6.17_1.2174_FC5
> [thl at notebook ~]$ sudo rpm -ivh /home/thl/tmp/testrepo/kmod-foo-1.1-1.2.6.17_1.2174_FC5.i686.rpm

> WARNING: Module /lib/modules/2.6.17-1.2174_FC5/extra/foo/foo.ko is not an elf object
> [thl at notebook ~]$
Now disable the plugin:
> [thl at notebook ~]$ sudo yum --noplugins --enablerepo=testrepo update

Disabling the installonly-plungin in
/etc/yum/pluginconf.d/installonlyn.conf has the same effect. So the "old
modules get removed on updates" problem in reality is a bug AFAICS.
Or I'm probably doing something really wrong here -- but what?
