Recover iso-image-create script
This script was removed from IPA with CoreOS support, but it seems to be quite generic. Recover and document it. Change-Id: I014ada4509e60541bf12ef2bce9915afd8858d54

ISO Images
|
||||
~~~~~~~~~~
|
||||
|
||||
Additionally, the IPA ramdisk can be packaged inside of an ISO for use with
|
||||
some virtual media drivers. Use the ``iso-image-create`` utility, passing it
|
||||
the initrd and the kernel, for example:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
./tools/iso-image-create -o /path/to/output.iso -i /path/to/ipa.initrd -k /path/to/ipa.kernel
|
||||
|
||||
This is a generic tool that can be used to combine any initrd and kernel into
|
||||
a suitable ISO for booting, and so should work against any IPA ramdisk.
