I tumbled into the following problem. I have an RKE2 cluster installed on openSuSE microOS. I deployed kafka on it with cruisecontrol. The kafka fired up properly, but cruisecontrol cannot monitor the kafka cluster. Upon closer inspection it turned out that cruisecontrol expects a unified cgroup hierarchy in the underlying operating system. I fired up google to learn that specifying systemd.unified_cgroup_hierarchy=1 as a kernel parameter should fix the problem, but actually it does not. /sys/fs/cgroup still shows the original hybrid setup.
Did anyone here came across the same problem? If so, what was the solution?

You might take this question to the OpenSUSE folks?
