Although it's informed in several places [1][2][3] that it's not supported to use Extended Update Support repos in RHOSP, I believe the most important place to have this information is in the Installation Guide, which is the document most customers should be following to deploy the software. Although having the information in Release Notes[1] could be considered enough, I believe implementation details should always be in the installation guide. I understand that using EUS isn't exactly an implementation detail, but this may not be clear enough to every customer. 1: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html/release_notes/content_delivery_network_cdn_channels 2: https://access.redhat.com/node/493953 3: https://access.redhat.com/articles/2969081
I agree, there are 3 locations mentioned here[1] that could/should be updated: [1] https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html/product_guide/ch-rhosp-software#sect-subscriptions
