Workaround:

Description: I can see there is a small mention of creating cgroup in ch03s07 with no explanation of any errors or issues that might arise while executing this in the playbook.
The labs have not used it in the exercises ( ch03s08 ) .
Many learners are reading it and running their playbook and are having issues like :

cgroup change of group failed

that is not mentioned / explained in the course or used in the lab exercise to reproduce it.

can we include some error scenarios like this in the course or in the labs ? I am from expert chat and we are bound to restrict ourselves to the course and lab issues. I shared some RedHat KB article like https://access.redhat.com/webassets/avalon/j/includes/session/scribe/?redirectTo=https%3A%2F%2Faccess.redhat.com%2Fsolutions%2F4484901#state=6c6b1c01-af90-40b2-8cd1-314a987b44d4&session_state=8e001c3a-4b5e-455c-a311-1294fd977ff3&code=2aad7fcc-fef7-435a-a008-892abe35b9a6.8e001c3a-4b5e-455c-a311-1294fd977ff3.4473e33a-bfd4-4fd0-9ebf-82faab4c2f6c for the cgroup issue but learners were not happy with it.
