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