-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a disk img for qemu that is 4G, but disk usage is only 650M ... due to how the image is created, it will grow to 4G, but only uses as much as it needs ... but, if I run a simple 'cp' on the file, it goes from: image: debian.img file format: raw virtual size: 4.0G (4294967296 bytes) disk size: 652M to: image: dtc.img file format: raw virtual size: 4.0G (4294967296 bytes) disk size: 4.0G Is there a way of moving things around such that it *maintains* the holes, instead of fills them in?
