Epic Goal

• Support RHEL-9 cluster nodes

Why is this important?

• OCP is transitioning to RHEL-9 and because FIO mounts the host FS, stores data there etc we need to make sure it keeps working

Scenarios

1. As an OCP admin, I want to upgrade from OCP version based on RHEL-8 to an OCP version based on RHEL-9 while keeping FIO working. A large number (all?) files are expected to change during the upgrade.
2. As an OCP admin, I want to install a fresh OCP cluster based on RHEL-9 and watch its file integrity

Acceptance Criteria

• FIO must support both RHEL-8 and RHEL-9 during the transition period
• Ideally we should test both RHEL-9 and RHEL-8 based clusters in CI, not sure if that's feasible

Dependencies (internal and external)

1. OCP must be installable with RHEL-9 for us to be able to test the operator

Previous Work (Optional):

1. The CaC team has been busy working on RHEL-9 STIG draft. Chances are they tested AIDE on RHEL-9 at least standalone.

Open questions::

1. Do we need to rebuild the aide container atop RHEL-9 or even keep both as long as OCP supports both RHEL-8 and RHEL-9? I don't think so, but worth keeping in mind
