In mainline, AFAIK no.  The vserver patchset, on the other hand, adds a new
xattr, iunlink, that copies the whole file when needed.  That works on most
filesystems.

That's quite a hack, though, and I think you'd be better off using btrfs
which does cow transparently at a lower level than hardlinks.
