Hi Uwe.
A simple reposync is fine, actually. My suggestion would be to drop the `--arch=noarch` flag you've specified. Our mirror manager likely will not respond to that request. `--arch=x86_64` by itself or no arch flag at all should be fine.
As an aside, the kickstart repos are actually a "point in time" set of repos, where they never update for the entirety of a minor release's 6 month life. This means it's when Rocky 8.X (in this case, 8.5) was released and some users want a baseline to start with instead of just installing everything brand new right away.
