History

Steve Baker e129fad7f8 Move reset-bls-entries to post-install 03-reset-bls-entries was previously a pre-install script to run after the machine-id was set, but a new kernel may be installed during the install phase, which will install another bls entry file with a filename which differs from the machine-id. This means this package installed bls file won't be updated when grub2-mkconfig is called, resulting in incorrect kernel args and boot device in the entry file that will get booted by default. By fixing the filenames after the new kernel is installed, grub2-mkconfig will update the bls file that actually gets used on boot.

Use RHEL cloud images as the baseline for built disk images.

Because RHEL base images are not publicly available, it is necessary to first
download the RHEL cloud image from the Red Hat Customer Portal and pass the
path to the resulting file to disk-image-create as the ``DIB_LOCAL_IMAGE``
environment variable.

The cloud image can be found at (login required):
RHEL8: https://access.redhat.com/downloads/content/479/ver=/rhel---8/8.0/x86_64/product-software
RHEL7: https://access.redhat.com/downloads/content/69/ver=/rhel---7/7.1/x86_64/product-downloads


Then before running the image build, define DIB_LOCAL_IMAGE (replace the file
name with the one downloaded, if it differs from the example):

.. code-block:: bash

   export DIB_LOCAL_IMAGE=rhel-8.0-x86_64-kvm.qcow2

The downloaded file will then be used as the basis for any subsequent image
builds.

For further details about building RHEL images, see the rhel-common and
redhat-common element README files.
