Hi Stephen,

I took a look at this possibility and it seems very powerful but not so easy 
to use. Is there a way to make a netns that's like a "child node" of another 
netns, and inherits all the settings of the default one, unless I configured 
separate settings for this "child netns"? Otherwise the netns has to duplicate 
everything already configured on the host system even if it's unchanged from 
the standard settings.

Thanks,
Matthew.
