Way ahead of you. I wrote my sparsify utility for ext2 in 2004: http://intgat.tigress.co.uk/rmy/uml/sparsify.html It's mostly of historical interest now, I suppose. The sparsify utility doesn't work on ext4 and I long since gave up maintaining the kernel patch. I still use the zerofree utility, though. It would be nice to have a modern version of sparsify. I'll try it out.
