Hi Jeff,
thanks again for your help. We chose to add a script (in the flavor the reset-handler) which is run at each boot. It checks whether a file exists on the rootfs-partition. If the file does not exists it assumes the very first boot after an rootfs-upgrade and creates the file and does what it has to do in regards to the ipk-files. IPK files are stored in /var/config.
Doing it like this we can add features and fix bugs in this scripts and they take effect with the very next upgrade of the rootfs-image.
Thanks again for your help.
