See this recent response, https://lists.fedoraproject.org/pipermail/livecd/2015-May/007723.html It is important to understand that Fedora LiveCD technology is based on embedded filesystems, an ext4 filesystem and partition (inside the ext3fs.img file) that is compressed inside a SquashFS filesystem (inside the squashfs.img file) all saved on the LiveCD or .iso file in an ISO 9660 filesystem, or on a LiveUSB device in the LiveOS folder of the device filesystem (which may be a fat, extX, or other filesystem). With this technology, when one sees or thinks about a file or filesystem size, one must be careful and clear about which of the many simultaneously present filesystems one is referring to. --Fred -T
