@moolitayer how do you do this in containerland? Is by default everything openscap enabled? Would it make sense for you to use the support feature mixin as well?

[moolitayer]

When a user scans a ContainerImage, we always run both an OpenSCAP scan & and a package scan[1] @durandom. We don't need to make that distinction ATM.

@aufi do you already have a corresponding PR in the UI and openstack?

[aufi]

@durandom Not yet, should I create a placeholder WIP PR for reference in OpenStack repo?

[durandom]

👍 from me

@miq-bot assign @agrare

@agrare please merge if you are ok with it

@moolitayer once this is merged, you might want to add supports :open_scap to the container base models or if you are using subclasses to the subclasses
