Mkisofs
From Knoppix Documentation Wiki
The mkisofs tool is used for premastering iso9660 filesystems which are used on CD or DVD. The output of mkisofs can be used in two ways. One, a file can be created for later recording onto a blank CD media. Two, mkisofs and cdrecord can be chained together with a pipe. The output of mkisofs is then sent to a CDROM writer with a utility such as cdrtools
Ya'll we could use some example commands here for easy reference.
