[SOLVED] systemd 247.1-1 - Failed to migrate controller cgroups

After upgrading systemd earlier today, I find the following warning in the log:

Dec 03 00:08:15 arch systemd[629]: -.slice: Failed to migrate controller cgroups from /user.slice/user-60001.slice/user@60001.service, ignoring: Permission denied

My user account is managed by homed. Is this warning specific to my setup?

I am aware that this is a warning and nothing seems to be broken but I would like to understand the issue.

Is the warning still present if you boot with the parameter systemd.unified_cgroup_hierarchy=true

Thanks for the hint. With this parameter, the warning is gone. I need to dig deeper into cgroups.

Sorry  for necrobump, but I'm having this same issue.

Could you explain how (or where) to set the systemd.unified_cgroup_hierarchy parameter?

Thanks.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
