| 34 | Create a bootable ISO image |
| 35 | |
| 36 | This plugin creates a hybrid, legacy and EFI bootable ISO image. The |
| 37 | generated image can be used on optical media as well as USB media. |
| 38 | |
| 39 | Legacy boot uses syslinux and EFI boot uses grub or gummiboot (not |
| 40 | implemented yet) as bootloader. The plugin creates the directories required |
| 41 | by bootloaders and populates them by creating and configuring the |
| 42 | bootloader files. |
| 43 | |
| 44 | Example kickstart file: |
| 45 | part /boot --source isoimage-isohybrid --sourceparams="loader=grub-efi, \\ |
| 46 | image_name= IsoImage" --ondisk cd --label LIVECD --fstype=ext2 |
| 47 | bootloader --timeout=10 --append=" " |
| 48 | |
| 49 | In --sourceparams "loader" specifies the bootloader used for booting in EFI |
| 50 | mode, while "image_name" specifies the name of the generated image. In the |
| 51 | example above, wic creates an ISO image named IsoImage-cd.direct (default |
| 52 | extension added by direct imeger plugin) and a file named IsoImage-cd.iso |
