[Libguestfs] Question: resize: non-sparse copying of extended partition

Hello everyone! I faced an issue using virt-resize. I have an image with extended -> logical -> pv -> lv -> ext4 (although I think LVM does not matter). And image is 65G virtual size and 1G actualSize. When I call virt-resize to 60G, it blindly copies the extended partition content, but does it non-sparse (resize.ml:1231), irrespective to --no-sparse option. So the destination image is 60G actual size. Is it a bug, or it was made intentionally (why?) ? TY for answers! -- Your sincerely, Maxim Perevedentsev
