I observe same behavior on slurm 23.11.5 Rocky Linux8.9..

> [root@compute ~]# cat /sys/fs/cgroup/cgroup.subtree_control                                                                                                                                         
> memory pids                                                                                                                                                                                            
> [root@compute ~]# systemctl disable slurmd
> Removed /etc/systemd/system/multi-user.target.wants/slurmd.service.

> [root@compute ~]# systemctl enable slurmd                        
> Created symlink /etc/systemd/system/multi-user.target.wants/slurmd.service → /usr/lib/systemd/system/slurmd.service.
> [root@compute ~]# cat /sys/fs/cgroup/cgroup.subtree_control
> cpuset cpu io memory pids

over time (i see this thread is ~1 year old, is here better / new understanding of this?

I notice the exact same behavior as Tristan. My CentOS Stream 8 system is in full unified cgroupv2 mode, the slurmd.service has a "Delegate=Yes" override added to it, and all cgroup stuff is added to slurm.conf and cgroup.conf, yet slurmd does not start after reboot. I don't understand what is happening, but I see the exact same behavior regarding the cgroup subtree_control with disabling / re-enabling slurmd.
