Hi, Thanks for the suggestion. However, I am not entirely convinced that this is worth effort and I have accordingly decided to mark it "wontfix". On the other hand, I have added "--reflink=auto" to calls to cp. For file systems supporting it (to my knowledge, sadly only btrfs does), it will now provide an constant-time copy'ing without the above side effects.
