Are you sure ? Last I remember, "cp -a" does not preserve some of the inode
data. Also, it does some file reordering.

Yes, most of these are inconsequential on a practical pov, but it is
still farther from cloning than using dump/restore.

Of course, if you want real cloning you would have to use "dd", but
that is _way_ beside the point here.
