Run a python script at kairos-install.pre stage

[rohitntnx]

Hi,

I have a kairos ubuntu image (kairos-ubuntu-24.04-standard-amd64-generic-v3.6.0-k3sv1.33.5+k3s1.iso) and I am adding a config.yaml and a python script into the iso using xorriso. Due to some limitation I am not able to use auroraboot to inject these. I have verified that the config.yaml and the script are successfully getting inserted into the iso image.

In the kairos-install.pre stage, I want to run the python script but I am not able to locate where my script is in the runtime environment. I tried following places without luck:

     /cdrom/**myfolder**/bin/**myscript**.py
     /run/initramfs/live/**myfolder**/bin/**myscript**.py
     /run/rootfsbase/**myfolder**/bin/**myscript**.py
     /mnt/cdrom/**myfolder**/bin/**myscript**.py
      /**myfolder**/bin/**myscript**.py

Is there a way to launch a shell and investigate while in one of the kairos stages?
Can someone please share the right path where the iso is mounted after boot?

In the grub menu, when you boot the ISO, just select the "manual install" option. That should drop you into a shell. You can do a find then.

Thanks for your reply. I have closed this question and created a new one to explain more details on what I am trying to do.
Here is the topic: #3858
I want the installation to happen automatically on all nodes.
