Comment 12 for bug 1970257

Did a quick change on packer-maas Kickstart files, turning BLS off:

Then downloaded the latest RHEL 9.2 and 8.8 DVD ISOs and created new images for MAAS:

$ maas homelab boot-resources create name='custom/rhel-9.2-20230912-no-bls' title='RHEL 9.2 20230912 No BLS' architecture='amd64/generic' filetype='tgz' base_image='rhel/9' content@=rhel-9.2-20230912-no-bls.tar.gz

$ maas homelab boot-resources create name='custom/rhel-8.8-20230912-no-bls' title='RHEL 8.8 20230912 No BLS' architecture='amd64/generic' filetype='tgz' base_image='rhel/8' content@=rhel-8.8-20230912-no-bls.tar.gz

After that performed two deployments (9.2 / 8.8) using the "custom" disk layout and then two extra deployments (9.2 / 8.8) with the default Flat disk layout and all tests worked w/o an issue.

Best,
Alan
