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.
