Fix ignition documentation missing information?

[gtherond]

Hi team!

Would it be possible to add a section within the ignition documentation page that would clearly state the expected path within the flatcar image where ignition json file is supposed to be present? I was looking for the information and was required to look for alternative places to get it (like, within the "Customizing image" page ) and then explore the various partitions looking for a .ign file.

I think that it may be easier for everybody if we could get right from a bat the information.

Thanks!

Hello @gtherond and thanks for the issue!

Can you elaborate on your use-case? Usually Ignition is provided via the QEMU helper or via user-data for cloud images and it is not supposed to be set by hand except when customizing the image or installing Flatcar via the flatcar-install script (that knows this location for you: https://github.com/flatcar/init/blob/ed0ce5ab08d77ff8fa775975961987ae2704fb34/bin/flatcar-install#L755)

Hi @tormath1 I'm using flatcar with baremetal and custom OEMing it, so we try to be sure we have all the correct information about ignition location.
