Sorry, seems I got distracted at that point.

Yes, that would probably fit in well ;-)

/me thinks about this for a moment -- Yeah, seems you are correct.

I should have thought of that.

There is still one thing in my mind and I'd like to get other opinions
on it:

Should we have add a %{?kmod_per_package_add-on} into the output that
get_rpmtemplate creates? *If* a spec file needs something special in
each kmod package it could add a

%define kmod_per_package_add-on put stupid things here \
 probably even with newlines in them

in the spec file and get that part included in each kmod-Package.

Take for example the nvidia-drivers of a well known 3rd party repo: they
currently have a
Conflicts:  kernel-module-nvidia-legacy-%{kernel}
in them -- that would not be possible with the new scheme and that
sounds like a problem to me.

They also have some special things for %pre and %post which lead to the
question: Do we also need something like 

The whole kmodtools function would look like this (original stuff

Yeah, sounds good.

Creat, thanks! Looks quite good.
