Mkisofs ---- make file system lager than 4G

mkisofs is an utility that creates an ISO 9660 image from files on disk.

From the man page for mkisofs, “mkisofs is effectively a pre-mastering program to generate the iso9660 filesystem - it takes a snapshot of a given directory tree, and generates a binary image which will correspond to an iso9660 filesystem when written to a block device.”

Developers of operating systems will mainly be interested in creating ISO filesystems for bootable CD, DVD, or BD via El-Torito. Nevertheless, ISO filesystems may also be booted from hard disk or USB stick.

Mkisofs, its Clone, and its Emulator

The program mkisofs is part of the cdrtools project by Joerg Schilling.

Some quarrels with the GNU/Linux community caused a fork of cdrtools, named cdrkit. The corresponding fork of mkisofs is named genisoimage. You will find it installed as “mkisofs” on many popular GNU/Linux distributions.

prog="genisoimage"

An independent alternative to mkisofs is xorriso, which has an emulation mode that understands the options which are used with mkisofs for producing a bootable ISO 9660 image. Most distributions have it either as package “xorriso” or as part of “libisoburn”. GRUB2 script grub-mkrescue depends on xorriso-0.5.6 or newer.
