This is a photograph captured in a supermarket. This shows a Linux machine that must be meant for showing advertisements or other videos and it is instead depicting a Linux bootup error. The filesystem has an inconsistency and this means that the fsck utility must be run manually to fix the error. Not a major issue as long as the drive is not failing. If it is a magnetic drive, this means that you hear a click of death, this means back up all data and replace it right away. But this machine is running Gentoo Linux, I have had a lot of issues with that distribution. Better to run Fedora in a business environment. Although Ubuntu Server is very good.
Below is another picture, an ATM running Windows 7. This machine is asking for Windows activation. Please just enter the product key…
