Hello there, from this serial console log, it seems that cloud-init does start executing when I add my own cloud.conf file in my gadget, but it does not execute my cloud-init config, but seems to break before it. See below:

With ubuntu-image command, I did not disable console-conf… is this the way, or am I missing something?
My custom gadget cloud config is copied over to the root of my gadget, with the name cloud.conf. gadget’s confinement is strict, with the model file’s grade set to “dangerous”.
I mounted the intalled image onto my linux box, and found my cloud-init config under 80_gadget-something.cfg, so I can confirm that it is on the filesystem, but never executed at boot time.
All-in-all, it seems that cloud-init is breaking with some outdated config, and seems to never execute mine afterwards?
