This is what I have come up with.
It creates an XML-type configuration file, and you can create your hooks.

It should work in such a way that for example, mpich package would 
provide the /usr/lib/update-cluster/mpich.updatelist

# update the config files..

for SCRIPTS in $(ls /usr/lib/update-cluster/*.updatelist); do
  test -x $SCRIPTS && $SCRIPTS ;
done ;

Yes. This is a good idea.
