Somewhere in March we got an update in that makes our shutdown look different.
We see now a lot of strange lines.

Nick Petrov went to look for a solution and found a way to hide these messages.

Follow his procedure:

Edit the file /etc/mkinitcipo.conf with sublime-text and add “shutdown” to the hooks. Then save it.

Then run the following code in the terminal

When you have rebooted, you will see less lines when you shutdown.

There is no need to do this. It is just for cosmetic reasons.
