2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack members of the community for any reason.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
- These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudo
in Windows.
- No porn. Even if you watch it on a Linux machine.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
Please report posts and comments that break these rules!

Can a linux/systemd nerd explain what the error is? I know it's a shutdown sequence, but I'm curious on the fault
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.
