Thanks for this reply, Allen.
To clarify, what I (and I think, all *8/EL-alike users) want is simply for the repos provided by Uyuni behave to the clients as the master repos do. We don't need any additional external settings or behaviours, we just want our systems to be able to get the same information from Uyuni as they would from the master repo that Uyuni is syncing from.
Currently, for repos like Centos8-AppStream, they don't because: Modules.
I'm seeing more *8 individual repos moving to Modules too, like MariaDb 10.5 whose Centos 8 repo depends upon modules, so this problem is one that is only going to grow.
I am definitely not a fan of this move to modules, I was quite happy with the traditional way, but there it is. I have a little soft toy that I stick a new pin into whenever modules cause me a problem. It's now more metal than plush.

When you refer to the "Content Lifecycle Management Process", I assume you mean cloning repos from a particular day, making changes, and associating those with the managed server, instead of the live once that is being synced? That is a whole other process that has to be implemented, just to work around this. Luckily, we only have a small handful of non SUSE or openSUSE systems to deal with this problem on, but having to clone and maintain repos for them is not really feasible. I can't imagine it being an option for someone with hundreds of CentOS 8 systems, who isn't doing this with current systems.

Hello,
The recent Centos 8.4 release appears to have triggered more issues for us, and made me review how we manage our Centos 8 clients. We plan to move to Rocky soon but the same issue will persist there.
Currently: Uyuni syncs Centos repos. My workaround so far has been to run "dnf -y update" on a schedule to each client instead of patching from within Uyuni as we do with Centos7. This pulls packages from the Uyuni mirror and has largely worked okay, but not any longer - lots of module related issues on all C8 clients since I updated the repos to 8.4. I'm not clear exactly why this has triggered this problem re-appearing, but it has. My understanding of this is that Uyuni doesn't update the module metadata when it populates its repositories, so the clients can't see this and fail.
We as Uyuni team recommend consuming AppStream repositories through the Content Lifecycle Management process so that you can benefit from all the features that SUMA UI provides. However, I understand that the method you described above can be preferred for smaller environments as it is more agile and direct. For that reason, we'd like to keep this as a valid option for those who prefer this approach. Basically, I'd like to see this working in the upcoming updates of any modular repository as well. So, please feel free to open an issue on GitHub, describing the actual problem you're having in detail, and we can work towards fixing it.
I've read about the Uyuni method of using the Content Lifecycle and have trialled this. This does work, but we don' t particularly want to be manually doing this for each Centos update or patch cycle. We're not big enough to warrant a corporate approval cycle for Centos, so updates are directly applied to our servers. (This has resulted in relatively few issues)
The only other method I can think of is to change the clients to having local .repo files and pull updates directly from the Centos mirror. This obviously negates some of the benefits Uyuni brings to package management, but would work reliably.
So I'm wondering - how are the other Centos/Alma/Oracle/Rocky 8 users of Uyuni applying updates, and how have you overcome the module problems?
