When starting and then stopping cgconfig either with:

systemctl start/stop cgconfig.service

service cgconfig start/stop

a shutdown or reboot after (later)  will hang.

# service cgconfig status
output shows:

A future libcgroup1 update will include the patch to resolve the problem.
Customers affected by this issue can contact SUSE Technical Support to request a PTF (temporary fix).


cgclear which unloads the cgroup filesystem clears all hierarchies, umounts their controller (subsystems), including subgroups in the systemd hierarchy which as a result breaks systemd.
