Package: gzip Version: 1.3.12-6 Severity: wishlist Sometimes there's a need to compress a sparse file. The typical use case for me would be a QEMU/KVM disk image file. It would be great if gunzip would have a --sparse option to write a sparse file when uncompressing, if the output is to a file and filesystem that supports it, and if not, writing a block of zero bytes instead. This way, doing "gzip foo.img && gunzip foo.img.gz" would not make the uncompressed file use more disk space than the original one.
