  I would say take the first one only and set just that.

  For many properties (e.g cpu freq, ram, storage size etc) I think a
negative value (-1) would do, for others we can choose an insane
number like -G_MAXINT for example. Not sure about booleans though. Do
we really need to check if value is provided btw? AFAIK, every
node/attribute has a default value.

  Awesome! Maybe its much more sooner that I starting really using the
gconfig part then. :)
