This example uses a tool called "xorriso" that can be added to Ubuntu via standard apt repos:

sudo apt install xorriso -y

Create the Answer File

The Answer file utilizes yaml with an example included in documentation:

https://stormagic.com/doc/svhci/2-4-0/en/Automate/create-answer-file.htm?Highlight=answer%20file

My example is included below:

installation:
  hostname: "svhci-answerhost-01"
  domain: "ts.stormagic.com"
  password: "St0rMag1c!"
  license_key: "MPGM-ILRW-ORDZ"
  eula_accepted: true

network:
  ntp: "time.stormagic.com"
  nameserver: "10.40.0.254"
  management:
    ip: "10.40.0.100"
    netmask: "255.255.255.0"
    gateway: "10.40.0.254"

storage:
  install_disks:
    - "/dev/sda"

post_install:
  shutdown_on_success: true

Modify the ISO

From a folder with the ISO and answerfile in together run the command

xorriso -dev ./cdrom.iso -boot_image any keep -map ./af.yaml /etc/answerfile.yaml --

My example below to remake the ISO file including the answer file:

root@mchristie-Ubuntu:/home/mchristie/Downloads/svhci-2-4-0_iso# xorriso -dev ./stormagic-svhci-6.7.U1.55194-cdrom.iso -boot_image any keep -map ./answerfile.yaml /etc/answerfile.yaml --
