Debian ISOs have all their big data files compressed: kernels, initrds, packages. There's not much potential for compression gains: $ cat <debian-12.0.0-amd64-netinst.iso | wc -c 773849088 $ gzip -9 <debian-12.0.0-amd64-netinst.iso | wc -c 756547037 $ bzip2 -9 <debian-12.0.0-amd64-netinst.iso | wc -c 759482932 $ xz <debian-12.0.0-amd64-netinst.iso | wc -c 743924568 This potential can only partly be exploited. ISO 9660 metadata cannot be compressed or else the bootloaders and Linux could not read the filesystem content. One could use zisofs compression for the few uncompressed files outside of what the bootloaders need to read. The Linux kernel would transparently decompress them. Have a nice day :) Thomas
