Viewing an Ignition file for a running system

I’m looking at an existing CoreOS installation and trying to determine if/where the systems ignition file is stored? I’m using this as an example and it would be helpful to reconstruct the ignition configuration.

Is the ignition file stored on the running system somewhere?

It isn’t. Before the first reboot, a parsed version of the config is stored in /run/ignition.json, but it’s not a verbatim copy of the config we fetched. After a reboot, it isn’t stored anywhere.
