Table 1. Options Used for mkisofs

-r Rock Ridge extensions, with file ownership set to more useful values. You also may need to look into the -R option, which is the same but does not modify the file ownership.
-T Generates the TRANS.TBL file for each directory. This may not be needed, depending on your usage.
-J Joliet extensions. Useful if the CD is going to be read on another OS.
-V The volume label for the CD. This is what is displayed when you put the CD into a CD drive.
-b The boot image to use. This makes the CD bootable by making it an “El Torito” bootable CD.
-c Location, relative to the source path, of the boot catalog used for “El Torito” bootable CDs.
-o Location of the output image from the mkisofs command.
