Tomas Hozza a590dd7591 docs/news: reflect EC2 image changes in the RHEL-8.5 images note 
The `ami` image type was redefined based on the official RHEL EC2
images. In addition, two new image types `ec2` and `ec2-ha` were
defined. These new image types are by default not exposed via Weldr
API.

Update the docs/news/unreleased entry related to RHEL-8.5 main images to
reflect these changes.

Add support for RHEL 8.5 main image types

OSBuild Composer can now build RHEL 8.5 images. The following new image types are supported:

  • qcow2
  • vhd
  • vmdk
  • openstack
  • ami
  • ec2
  • ec2-ha

RHEL-8.5 AWS images

The ami image type have been redefined based on the official RHEL EC2 images.

Notable changes compared to RHEL-8.4 are:

  • the default user created by cloud-init is ec2-user
  • NTP client configuration uses 169.254.169.123 NTP server by default
  • the boot mode was changed from hybrid to legacy only

The ec2 and ec2-ha images represent the official RHEL EC2 images, which are produced as part of RHEL release. These contain RHUI client packages, which are available only from within Red Hat internal network. For this reason, these image types are by default not exposed via Weldr API (in the on-premise use case) for all RHEL releases.

This default configuration can be overridden by placing the following line in the osbuild-composer configuration /etc/osbuild-composer/osbuild-composer.toml:

[weldr_api.distros."rhel-*"]
# no lines below this section
