This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.

== Summary ==
Offer Fedora IoT users a new method to create and deploy customized
Fedora IoT disk images using a new installer called Simplified
Installer.

== Owner ==
* Name: [[User:runcom| Antonio Murdaca]], [[User:pwhalen| Paul Whalen]]
* Email: [e-mail], [e-mail]

== Detailed Description ==
The Fedora IoT Simplified Installer will use coreos-installer to write
an OStree raw image straight to a disk specified in a kernel argument,
without the need for a kickstart or user interaction. This type of
installation is ideal for devices connected at the edge where
connectivity can be slow or intermittent. It offers the ability to
configure the system via osbuild itself, FDO and Ignition.

== Feedback ==

== Benefit to Fedora ==
The addition of the Fedora IoT Simplified Installer will benefit IoT
users by allowing them to create customized disk images for use on
their edge devices. This feature is already available downstream,
adding it to Fedora will once again bring Fedora back to the true
upstream of RHEL for edge and allows testing and adoption of new
functionality like FIDO Device Onboarding.

== Scope ==
* Proposal owners:
** Test building Fedora IoT Simplified Installer with `osbuild-composer`
** Update Fedora IoT documentation with usage instructions.

* Other developers:

* Release engineering:
* Policies and guidelines: N/A (not needed for this Change)

* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives:

== Upgrade/compatibility impact ==
* Not applicable to this change.

== How To Test ==
Testable by installing `osbuild-composer` in Fedora 38 and using the
command line tool or the Cockpit web interface to create a Fedora IoT
Simplified Installer iso to deploy a UEFI enabled edge device.

== User Experience ==
This change will greatly enhance the Fedora IoT user experience by
allowing users to utilize `osbuild-composer` and blueprints to create
customized Fedora IoT deployments and leverage new features like FIDO
Device Onboarding for secure zero touch device onboarding of edge
devices as well as Ignition to configure the device once it starts.

== Dependencies ==
N/A (not a System Wide Change)

== Contingency Plan ==
* Contingency deadline: Beta
* Blocks release? No.
* Blocks product? No.

== Documentation ==
* Usage documentation to be written and included in the
[https://docs.fedoraproject.org/en-US/iot/user-guide/ Fedora IoT user
guide].

== Release Notes ==
