LAB_2.6.pdf Figure 2.28 is incorrect

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
Loaded: loaded (/etc/systemd/system/foo.service; disabled; vendor preset: disabled)
Drop-In: /etc/systemd/system/foo.service.d
└─00-foo.conf
Active: active (running) since Mon 2020-03-30 13:17:37 CDT; 8s ago
Main PID: 5471 (stress)

└─5474 /usr/bin/stress --cpu 1 --vm 1 --io 1 --vm-bytes 128M

Thank you for pointing this out, Lee
