Michael Raskin has been right. Having an atomic operation is a design
goal. I've forgotten about that.
Anyway:
time cp -RP .nix-profile .nix-profile2
shows < 0.01s
This just copies the top-level symlink, so it's a O(1) time operation. Try
$ time cp -prd .nix-profile/ .nix-profile2
real 0m0.692s
user 0m0.036s
sys 0m0.528s
