Yes, Yes, Yes, and Yes. I'm making the assumption that the common
case will be with a veth device in the container and that all of the
aforementioned attributes should be copied over. In the future case
where we could potentially have a real device in the container, it
probably doesn't make sense to copy the mac address.

I'm sure it's possible, but no, I haven't planned out everything for
the next year. If you have strong feelings about what should be done
in user and kernel space, feel free to share :)

DL> Argh ! I was hoping there was something else than the source code

The header file makes it pretty clear what is going on, but maybe the
Documentation/checkpoint/readme.txt will help. Putting all the
details in such a documentation file would be rather silly at the
moment, given that new things are being added at a rapid rate and it
would duplicate the only description that matters, which is the
header file.
