I like the idea of your new patch, a lot of things can be fixed in that way.
Ok, I will remove the extra code to remove (%preun) in the patch.
Just a comment about your patch: for openSUSE /boot/initramfs-* files are
called /boot/initrd-* and maybe someone would not require it (i.e. embedded
systems). If it is created it is normally removed and it might not be
necessary (although I like your idea to control it).

> I just asked you to fix up the code as I suggested in v4.
Now I understand why no code was added in %preun.
Ok, your suggestion was very good, but let me try and explain better with
commands what I would like to fix after next point. When I said 'update'
wasn't clear, I think.
If it doesn't fit with your idea or global usage, I will include your
suggestion like it is.

I was refering to the cases when zypper is used to install a new kernel with
the same release and different build number or when 'rpm -i --replacefiles' 
is used (in this case it would be necessary to remove the old kernel with
'rpm -e --justdb' too).
In this cases we only need the possibility of copying the files from the new
package and not only if they don't exist.
I have thought about an easy way (no extra or problematic command) and I think
I have it.
In addition to your suggestion (if the file does not exit in /boot), I will
just compare the file in /boot with the file in /lib/modules/%{KERNELRELEASE}
and if it is not the same, we allow copying:
%post
if [ -x /usr/bin/kernel-install ]; then
        /usr/bin/kernel-install add %{KERNELRELEASE} /lib/modules/%{KERNELRELEASE}/vmlinuz
fi
for file in vmlinuz System.map config; do
        if [ ! -e "/boot/${file}-%{KERNELRELEASE}" ] || ! cmp --silent "/lib/modules/%{KERNELRELEASE}/${file}" "/boot/${file}-%{KERNELRELEASE}"; then
                cp "/lib/modules/%{KERNELRELEASE}/${file}" "/boot/${file}-%{KERNELRELEASE}"
        fi
done

Let me try with a new patch to know your opinion.

Thanks

Best regards
José Ignacio
