CentOS Stream 9 already has stratisd 3.2, so that will probably be what's in RHEL 9.1.  I'd just sit tight and wait for that to be released, should be soon based on the release history (approximately six months after 9.0).

Is CentOS Stream 9 the only recommended way to get the new builds?

I'd like to get some of the new features in Stratis v3 builds on RHEL 9 but I'm not seeing them in the repo. I can manually install newer release rpms and dependencies. But that puts me into manual maintenance. 

Has anyone tested newer Stratis releases on RHEL 9 or do you all recommend just staying with only the builds included in the repo? 

I appreciate your input!
