Thanks, I understand this. However my curiosity in this topic got triggered by one application, Ethernet Configuration, found in Android-x86 2.2 & 2.3 under Settings category. This app can change the IP address. However on a typical Linux PC it can be done (using ifconfig) only with admin/root privileges. Of course it has nothing to do with installing kernel modules, but still it implies that an application can get root privileges. Isn't it so? I am anyway going to have a look at its code (http://www.android- x86.org/screenshot).
