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.
search for "linux fix bad bit", from my experience with raspberry pis i think this happens if you don't power off the device properly. if this happens more often, it's usually a sign that the hdd is damaged and will give in soon
That's just systemd failing to start Switch Root. Have you tried the systemctl status suggestion in the error, or reading the text file it generates?
It got too close to the Apples and was corrupted.
Well, it doesn't look like a core dump
My supermarket uses Arch btw.
I'm sure they announce it on their loudspeakers when you're in the store too.
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.
"Beware peasants! This store uses arch btw."
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.
Do they use a raspberry pi?
Or an Adafruit, perhaps?
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.
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
Why does this produce need a massive digital signage pylon?
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.
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.
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.
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)
Why would it run on a fruit?
Yes! Potatoes are the way, as our ancestors taught us!
So, an HP laptop?
Because it would be expensive, just look at the price of the Lime /s
They needed to construct additional pylons.
You need more minerals
Thanks Judicator Aldaris
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.
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
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.
You are correct. Ill add an edit. Thanks!
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.
It's been my experience that SD cards are almost always what causes a failure on a SBC. Given the cost of the screens, i'd probably choose something that could boot off nvme storage. Or at least tape a new, configured SD card to the case of the SBC for when this inevitably happens.
An SD card is MUCH less reliable than a good hdd unless it's read only.
