Description Alex Crawford 2019-12-12 18:46:14 UTC

s390x doesn't support the QEMU firmware config device that we use to pass Ignition configs through to RHCOS guests. As a fallback, libguestfish was used to modify the root disk to directly inject the Ignition config. This doesn't work on remote machines though, so the new approach is to use the RHCOS images built for OpenStack and to pass the Ignition config through the config-drive mechanism instead.

This BZ is just a formality as the code has already been merged. I'm moving this to ON_QA.
