iso
Generates a bootable ISO image from the kernel/ramdisk generated by
the elements baremetal or ramdisk. It uses
isolinux to boot on BIOS machines and grub to boot on EFI machines.
This element has been tested on the following distro(s): * ubuntu * fedora
NOTE: For other distros, please make sure the
isolinux.bin file exists at
/usr/lib/syslinux/isolinux.bin.
baremetal element
When used with baremetal element, this generates a
bootable ISO image named <image-name>-boot.iso
booting the generated kernel and ramdisk. It also automatically appends
kernel command-line argument
'root=UUID=<uuid-of-the-root-partition>'. Any more kernel
command-line arguments required may be provided by specifying them in
DIB_BOOT_ISO_KERNEL_CMDLINE_ARGS.
NOTE: It uses pre-built efiboot.img by default to work for UEFI machines. This is because of a bug in latest version of grub[1]. The user may choose to avoid using pre-built binary and build efiboot.img on their own machine by setting the environment variable DIB_UEFI_ISO_BUILD_EFIBOOT to 1 (this might work only on certain versions of grub). The current efiboot.img was generated by the method build_efiboot_img() in 100-build-iso on Ubuntu 13.10 with grub 2.00-19ubuntu2.1.
ramdisk element
When used with ramdisk element, this generates a
bootable ISO image named <image-name>.iso booting the
generated kernel and ramdisk. It also automatically appends kernel
command-line argument 'boot_method=vmedia' which is required for Ironic
drivers iscsi_ilo.
