The new/ tree is populated with hard links to corresponding objects in
old, which is what mv will do (on the same filesystem, anyway).
A popular answer to my original question claims that "cp -rl" creates a race
condition:

I now consider this a moot point, as such "race conditions" would be inevitable
with a recursive move operation. Thank you for the solution.
cp with --remove-source would just about obsolesce mv.
I noticed some of the source for mv comes straight from cp (e.g. cp_options and
cp_option_init).
