Likely none of them. The embedded menu is the most counter-intuitive thing in the whole kernel config. It does not supply a list of things you may enable, instead it activates a menu that allows you to switch stuff OFF that is normally ON. The rationale is that embedded devices need to get by on a very slim kernel and with some magic trickery they can successfully disable some features that are usually considered perfectly normal for regular desktop use. For example: CONFIG_HOTPLUG. It's unthinkable to remove this for a desktop, but does your TomTom need it? Does a GPS even have hotplug facilities? How about ADSL router/modems? To disable namespace, enable embedded, leave everything on, and you will find you can now disable namespaces. -- alan dot mckinnon at gmail dot com
