Description of problem:
A clean install of CentOS Stream 9 20210507.t.1 setups up "subscription-manager" and no repo files in /etc/yum.repos.d - this results in the following error when running "dnf update":

1. dnf update
   Updating Subscription Management repositories.
   Unable to read consumer identity

This system is not registered with an entitlement server. You can use subscription-manager to register.

Error: There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d".

There are two errors - no centos repoitory (which I've been told is expected) but also that the system is not registered. Together, these two errors would look like CentOS needs to be part of a subscription like RHEL to work.

Steps to Reproduce:
1. Basic install of CentOS Stream 9 - minimal install is all that's needed
2. Try "dnf update" after enabling the network interface and it fails
3.

Expected results:
Subscription-manager isn't required for CentOS - I would expect it to not be installed or at the very least disabled or made silent during normal dnf use.
