This section is relevant not only to RHEL 9, but all RHEL versions (6,7,8,9) and also architectures. Arch and OS version restrictions are already covered briefly in the procedure steps for creating custom products, but this section's title and content should be updated as well to reflect the true scope (all RHELs, and arch as well as OS version.) It should also be stated that arch and OS version restrictions are intended to be set only for custom products, as Red Hat repositories have these set automatically.

Looking at the procedure in 5.24. Restricting Custom Repositories to RHEL 9 in Satellite and the steps that are performed in the web UI, the procedure itself will also need some tweaking.
