Thanks! Yes, the search engines helped[1]. I run a minimal system, so when I mount cpusets, it will actually mount cgroups with a default mount option of "noprefix". But you likely run a rootfs with cgroups already, so it gets mounted directly without "noprefix". Then, when the logic analyzer tries to mount again, the implied default "noprefix" is discarded. [1] https://cgroups.vger.kernel.narkive.com/20fAhMNN/noprefix-mount-option So, I will update the script to mount "cgroups" instead of "cpuset" and use the newer filenames instead. This seems to be the proper way.
