In this case, we have an absolute pathname for the pointed-to file, so
there's no danger in making a symlink.  So how about: try hard
linking; if that fails with EXDEV, and if we have a full pathname for
the pointed-to file, use a symlink.  Otherwise give up.  Do we
generally have absolute paths in real-world cases?
