Sorry I wanted to say cross-packaging. Still I think using the system 
default tar program is a good way to go.

I agree.

Right, but I am more concerned about the proper way of doing it and not 
the difficulty. From all this discussion, using fakeroot directly does 
not look to me as the right solution for having "root" in the tar, in 
the first place. So if we are also able to get rid of the fakeroot 
machinery in cpack, maybe it would be a better solution.
