LAB_2.6.pdf Figure 2.28 is incorrect

surikoya

Small correction in LAB_2.6.pdf, Figure 2.28 is incorrect. CGroup should have been /foo.slice/foo.service. Appears to the same as Figure 2.25.

Can someone please confirm.

Hello Suriloya !

Yes, you are correct, the same image was used and that was not the intention. The correct information is as you pointed out the CGroup should be foo.slice/foo.service. The class notes have been updated, and the updates will be released the next time we update the course.

Here is what the correct image looks like on my test machine:

[root@centos system]# systemctl status foo
● foo.service - Example service unit to run stress

Thank you for pointing this out, Lee
