libpam-cgfs =========== In the past, Ubuntu carried a systemd patch to provide logged-in users with cgroups which they could administer. This can now be done by the pam_cgfs module. By default, pam_cgfs will create a new cgroup for the user for all controllers other than name=systemd, but if '-c ' is passed then only the listed controllers are handled. (controllerlist must be comma-delimited) The default list of controllers to handle is listed in /usr/share/pam-configs/cgfs, and is set to only freezer and memory. To edit the list, do so in /etc/pam.d/common-session. Note, this conflicts with the libpam-cgm module which also creates cgroups for logged-in users, but does so by talking to the cgmanager or cgproxy daemon.
