[Bug 1750031] Re: scary/unexpected output in adduser and deluser

[Scott Moser]

I've also tried a bionic azure image 
$ cat /etc/cloud/build.info 
build_name: server
serial: 20180222

It did not reproduce there.
So as far as I can tell it shows itself only on Azure 16.04 images.

- These are confusing at best and new in bionic.
