Can I get a filesystem cleanup on aisle 6?

Shit must look dystopian to anyone who doesn't understand what it is.
- I bet there was a granny, reading it line by line and crumple about where the fucking apples at.
  
  What u mean granny just grep 'apple' Duh
  Lmao
- 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?
- They needed to construct additional pylons.
  
  Thanks Judicator Aldaris
  
  You need more minerals
- 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?
  
  Because it would be expensive, just look at the price of the Lime /s
  
  Why would it run on a fruit?
  
  And not Windows*
  Macs are not worth it for stuff like this.
- Because flashy screens work on dumb lizard brains
  
  Well ya. That is why were are here in this thread right now. But also having a sign you can change easily is probably also useful.
- 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.
- Greed?
- 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.
  There's no need to be rude.
  
  Do you understand the meaning of the word "need?"
- Advertising, easier to see prices
- To attract bugs there instead of the food.
  
  But that's where the food is.

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
  
  The root filesystem mounted fine. That's why the init is starting with all the services on the root disk.
- 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.
- 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.
  
  So the weird block character in the "see... for details" line is replacing "nitrd-switch-roo" just to shorten the line? That's what I was trying to figure out.

Who doesn't love some kernel panic during shopping
- That's not a kernel panic
  
  any idea what this is? Ive been seeing this a lot when I start up my laptop - sometimes it goes away automatically, sometimes it doesnt, but I have no idea what to even search for.
- Or at the disco.
- how else r they gonna make popcorn?

Do they use a raspberry pi?
- Or an Adafruit, perhaps?
  
  Never heard of an adafruit SBC that runs Linux, but there's a ton of these SBC so it might be
- I prefer Key Lime Pie tbh
- Probably too small for systemd.
  I mean, I can hope smaller machines run smaller builds that can avoid systemd, at least.
  
  Rpi does use systemd tho....
  
  Raspberry pies are more powerful than you give them credit here. Nothing wrong with using systemd on them

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.
