two dpkg-instances / invoking module-assistant on kernel-upgrade

[Patrick Scharrenberg <pittipatti@web.de>]

Hi!

I built a source-package for module-assistant for a driver needed on boot.

Now I'm searching for a way to re-invoke module-assistant on 
kernel-upgrades.

My first try was to add a hook to initramfs-tools that launches 
module-assistant which works perfect when starting mkinitramfs manually.
But when installing a new kernel, this hook gets started while a dpkg is 
running, so I get a conflict, when module-assistant tries to invoke dpkg 
to install the driver-package it built.

So, what is the best practice to recompile kernel-modules on 
kernel-upgrades?
I'm looking for something like adding a package to install to the 
running dpkg-run or a possibility for post-dpkg-script or something.
I couldn't find anything on the net.

The only workaround I could imagine is to start m-a from an init-script 
on reboot/shutdown and then restart update-initramfs, but that would be 
very impracticable.

Any thoughts?

Thanks
Patrick
