+      Red Hat Enterprise Linux Beta releases are made 
+      available only for testing purposes. Red Hat provides 
+      these Beta releases and revisions as a courtesy to 
+      facilitate early testing by users prior to a Generally 
+      Availability (GA) release, and to solicit feedback 
+      from users on the Beta functionality. Red Hat does 
+      not support the usage of RHEL Beta releases in 
+      production use cases. NOTE: Beta cases are 
+      handled as Severity 4. Upgrading to or from any 
+      RHEL Beta release is not an upgrade path that is 
+      supported by Red Hat. Red Hat Enterprise Linux Beta 
+      deployments cannot be directly updated to a non-beta 
+      Red Hat Enterprise Linux release, or vice-versa.
       Template for Red Hat Enterprise Linux 9 VM or newer.
