In the second part of the user guide: https://codectl.io/docs/user-guide/airgap/
The table at the top lists several protocols to use for transfer but only 1 method is described on this page.
The method described on this page appears to be how to mirror the offline bundle into a RHCOS based registry node.
- I can't see where in the docs the steps are for creating this RHCOS registry node
- I'm doing a disconnected install following these docs so I wouldn't be able to see this node at all ( assume this is where the S3 or DVD methods would be flushed out)
