Note I found the installation media because the application linked to it. It may be good to keep the chapter in, but mention that installation media aren't used when Katello is present. That would also apply to upstream.

And I'd like @jeremylenz and/or @ianballou to have a look.

Then I can close this PR, because the note is already present:

ifdef::foreman-el,katello[]
When you install the Katello plugin, you can download packages from a Pulp mirror.
In this case, installation media are ignored.
endif::[]
ifdef::satellite[]
You can use this parameter to install third-party content.
Red Hat content is delivered through repository syncing instead.
endif::[]
