foo has a size of 0 bytes!
The user thinks he's replicating timestamp and permissions, and he's actually deleting data. (Well, the data is still in foo2, but...)
To be clear, when doing cp -a --attributes-only aaa foo (linked to foo2), the behaviour I expect is that foo and foo2 still point to the same inode as before, of course with their content unchanged, and that the attributes of both links now match those of aaa—like when you "chmod" or "touch" a link.
