* I don't really know how to deal with this nicely, so I will use a completly

* dumb method ;-)
|
|
* I will load the config file in memory, but skipping all the sections of the

* modules we want to save. Then I will create a brand new file, dump the file

* loaded in memory and then append the sections of the modules we want to
