| 25 | Create a bootable ISO image |
| 26 | |
| 27 | This plugin creates a hybrid, legacy and EFI bootable ISO image. The |
| 28 | generated image can be used on optical media as well as USB media. |
| 29 | |
| 30 | Legacy boot uses syslinux and EFI boot uses grub or gummiboot (not |
| 31 | implemented yet) as bootloader. The plugin creates the directories required |
| 32 | by bootloaders and populates them by creating and configuring the |
| 33 | bootloader files. |
| 34 | |
| 35 | Example kickstart file: |
| 36 | part /boot --source isoimage-isohybrid --sourceparams="loader=grub-efi, \\ |

| 39 | |
| 40 | In --sourceparams "loader" specifies the bootloader used for booting in EFI |
| 41 | mode, while "image_name" specifies the name of the generated image. In the |

| 43 | extension added by direct imeger plugin) and a file named IsoImage-cd.iso |
