The Register runs a regular series of reports on public signage showing crash messages instead of the ones they are supposed to show. Usually these are Microsoft Windows messages, often for hilariously out-of-date versions of Windows. This one, for a change <https://www.theregister.co.uk/2020/03/24/bork_walmart/>, shows a Linux boot failure. But it is still a hilariously out-of-date version of Linux.
