      Previously, the `coreos-installer` CLI tool did not correctly modify, reset, or show the kernel arguments for an ISO generated by the `openshift-install agent create image` command. For example, the `coreos-installer iso kargs show <iso>` command reported the following error: `Error: No karg embed areas found; old or corrupted CoreOS ISO image.` With this update, the following `coreos-installer` commands work as expected when querying an agent ISO:

       * `coreos-installer iso kargs modify <iso>`
       * `coreos-installer iso kargs reset <iso>`
       * `coreos-installer iso kargs show <iso>`

      Running the command coreos-installer iso kargs show no longer works with the 4.13 Agent ISO. Instead we get this error:

      $ coreos-installer iso kargs show agent.x86_64.iso
Writing manifest to image destination
Storing signatures
Error: No karg embed areas found; old or corrupted CoreOS ISO image.

      This is almost certainly due to the way we repack the ISO as part of embedding the agent-tui binary in it.

      It worked fine in 4.12. I have tested both with every version of coreos-installer from 0.14 to 0.17
