I've created a sparse file with dd. How do I copy contents of another file there, leaving all the zero blocks unallocated?
The solution is apparently to use cp --sparse=always. My first attempt was with writing some Python code, but unfortunately the MD5 sums didn't match (could anyone tell me why? the code's in edit history).
