Yes, systemd uses cgroups. I'm trying to understand if the Slurm use of cgroups is incompatible with systemd, or if there is another way to resolve this issue?
Looking at the man page for pam_systemd, it looks reasonably safe to disable this for logins on HPC compute nodes. I think you will also need to mask the systemd-logind service if you remove the pam module:
systemctl stop systemd-logind systemctl mask systemd-logind
