Non-interactive ISO installation

[ighsoh]

I understand that using a USB key, placing an answers.json file in the private directory you can automate SmartOS install, including the ISO based installations.
However I could not find any information on how this would be possible without the use of a USB key.

I see that there is a provision in smartos_prompt_config.sh for providing a custom path of an answers file, but since this is called by the system/smartdc/config service method at boot time, I am not sure how I could invoke it.

Is this even possible as of the current state of the configuration scripts?

That's only there for testing.

For an ISO there's currently no way. The problem is that it needs to get on the filesystem somehow, and it can't be loaded over the network because the network hasn't been set up yet when the answer file gets loaded.

Getting it onto the filesystem is not an issue since I could just simply create a new ISO with the answers already on there.

My case surely is unusual, therefore I am not against a PR, if this is something that is needed, it definitely is for me.

If you’re creating a new ISO then you can put it in private/amswers.json just like it would be for a USB.
