DoudouLinux CD » Migration to ARM

Currently the package doudoulinux-icons-diverted provides modified application icons for the full set of DDL applications. As we are now building ARM images and later we way build a DVD image, this package may provide icons for applications that are not installed. Moreover the DDL applications may not all be installed, eg. SuperTuxKart doesn't run on Genesi/Efika and should then not be installed on it.

As a result, as the package doudoulinux-icons-diverted cannot know in advance which application will be installed and when (the package can be installed before applications are), we need a package script that hides icons of missing applications. The trick can be to add the option NoDisplay=True to the *.desktop files of missing applications.

The best way to run this script seems to use package triggers as explained on the following pages:

• http://www.seanius.net/blog/2009/09/dpkg-triggers-howto/
• http://lists.debian.org/debian-dpkg/2007/04/msg00076.html

The trigger should listen to /usr/bin/ and /usr/games/ in order to detect the installation of new applications.
