Shit must look dystopian to anyone who doesn't understand what it is.

ALL SHALL BOW BEFORE THE DARK OBELISK OF TECHNOLOGY.
Some crusty broken distro install with a broken boot that may or may not be due to a bad disk or fs corruption is pretty much as dystopian as it gets.
And this comment is about as "First World Problems" as it gets.

My supermarket uses Arch btw.
I'm sure they announce it on their loudspeakers when you're in the store too.
"Beware peasants! This store uses arch btw."
Oh man I would do this all the time. When I worked a grocery store it had suse and later they switched to windows. Before if anything didn't work it was user error like rebooting with personal items left on the keyboard. After we had self checkouts that would bluescreen and other than myself only two people knew how to reboot them. If it had arch I would make sure everyone knew.
Why does this produce need a massive digital signage pylon?
No idea where it's from or what it usually looks like since I just nabbed this off of Facebook, but my guess is to display ads, or perhaps some slo-mo videos of fresh fruit being tossed in an appetizing manner in an attempt to trigger your Pavlovian reflex to buy some of those oranges.
Couldn't find any pictures of that particular setup operating under normal conditions, but here are some similar ones to give you an idea:
The question is, why does it run on Linux and not Apple
Perhaps it runs on a Raspberry Pi?
Or orange pi. Banana pi.
The best thing I learned when writing this comment (because I know there are other fruity labeled pi computers) is that you can look up “other fruit pi” and actually find results. Semi-relevant ones. (I use ecosia, not google/bing/askjeves, so ymmv)

Because it would be expensive, just look at the price of the Lime /s

Big Fruit is going to control our minds and enslave us all. If only they could get the interns to configure their shitty Linus distro.
Do you really want an explanation for why a market might want large signage that they can change without much extra labor? Seems self evident to me.
You could've just said:
So they can change the signage without much extra labor.

It got too close to the Apples and was corrupted.
Well, it doesn't look like a core dump
Can a linux/systemd nerd explain what the error is? I know it's a shutdown sequence, but I'm curious on the fault
It is actually a boot failure. Normally the kernel reads some config from the initrd (the bootloader loads initrd and passes it to the kernel - thanks dan) and then does a bunch of setup stuff, and then it mounts the actual root filesystem, and then switches to using that. In this case, the root filesystem has failed to mount.
Hardware failure is most likely the cause, but misconfiguration can also make this happen. Probably hardware though.
If its misconfiguration, an admin can reattempt to mount the root drive on /new_root, and then ctrl-d to get the init system to try again
ELI5: couldnt open C:/ drive
Edit: clarified what loads the initrd - as per dans comment.
Normally the kernel loads an initrd filesystem,
The bootloader (GRUB) loads the initrd, not the kernel. The kernel accesses stuff from the initrd, but it's already loaded by that point.

Thanks for that!
Switching to Linux and actually being able to see real time logs made me actually curious how it works, so that's one gear out of the machine demistified

These kinds of public errors are almost always a hard drive failure.
Using an actual hard drive for an embedded system like this would be a failure in and of itself.
Unless it literally has to store several hours' worth of HD video content, no reason the entire system couldn't fit on an SD card.
As someone who works on embedded devices: HDDs are used for media storage and can be easily replaced. Any NAND as a limited life span and good embedded software will try very hard to minimise writes. Though in my particular area, there's additional security constraints on the OS, which preclude any removable flash storage from being used.

Systemd has a feature to shorten lines too long for the display, which is a pretty stupid idea, as you can see here.
The service failing here would be initrd-switch-root.service.

Is this an actual video wall? Looked like bad CGI art. Kinda absurd.
Great post though.
I haven't seen this thing in action under normal conditions since I just looted the picture off Faceborg, but I imagine it probably shows a slideshow of ads.
I had a HDD fail on my media server and that screen gives me ptsd. I could clean it up with fsck for a while, but it meant plugging a keyboard and monitor into the box. A huge PIMA, I should have swapped out that drive the first time it happened.
You didn't immediately swap the failing drive? I feel sorry for the media server. It was trying it's best
Do you not like sound of the read head scraping against the platter on spin up? Weirdo... It's a rare treat, so you have to appreciate it while it's there.
Neat, I saw a price scanner at Walmart with an Android error today
Oh man, I WANT THIS THING! That is what I call a cool feature in home design. Time to think how to do it relatively cheaply in my study...
This is an old image
Very intreasting. But can it run doom?
If a literal toaster can do it, I'm sure this thing probably can as well.
