I thought I would never have to see BSOD after switching to linux, but here we go...
[ tbh, I love that errors are presented much better, just that the name doesn't bring back much good memories.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It makes sense to use the words that people are most used to, and bluescreen/BSOD has been the go-to lingua for describing a crash/error screen - even if not blue - since a while now.
Finally, my life is complete. We have achieved feature parity with Windows.
Seriously, the BSOD QR-code is a great way to have a more inclusive system. Hardened geeks can still sift through the boot log to find problems and newbies can just get help online. Win-win.
Win-win.
I see what you did there.
I hope it supports themes. I'd like to make my BSOD look like the classic Windows 9x BSOD.
The systemd-bsod will also display a QR code for getting more information on the error causing the boot failure.
That’s pretty neat. Nowadays with the proliferation of smartphones that’s an easy way to move straight to troubleshooting the issue
scan qr code
ERROR_SXIFKK_INV_MEM_0
troubleshooting link is just a jpg of a frowny face
This is the best summary I could come up with:
Systemd 255 even is introducing systemd-bsod as a "Blue Screen of Death" for displaying important error messages during boot failure, systemd-vmspawn as a new tool to spawn virtual machines, and other new features.
It's not an off-timed April Fool's prank or anything, there is finally a systemd-bsod service for "Blue Screen of Death" full-screen error messages on Linux...
-
Systemd's bootctl will now show whether the system was booted from a Unified Kernel Image (UKI).
-
systemctl will now automatically soft-reboot into a new root file-system if found under /run/nextroot/ when a reboot operation is invoked.
-
A new option "SurveFinalKillSignal" has been added to skip the final SIGTERM/SIGKILL spree on shutdown in order to survive soft-reboot operation.
-
A new "ConditionSecurity=measured-uki" option for only running when the system has been booted via a measured Unified Kernel Image (UKI).
The original article contains 520 words, the summary contains 139 words. Saved 73%. I'm a bot and I'm open source!
Hibernation into swap files backed by Btrfs are now supported.
I know Btrfs people have been waiting for this for quite a while.
This has been a thing since Linux kernel version 5.0.
This is our chance to out-UWU the :( windows bsod
Come on all you Linux furries, bronies, etc. I know you can do it
What the actual fuck?
My thought exactly.
When would this be triggered? Could it be used during kennel panics?
No, kernel immediately stops execution of all normal processes once it gets into a kernel panic, and there's no way for processes to hook into this functionality. It is intended to be the emergency stop state when the kernel realizes it doesn't know what's going on and it would be dangerous to continue executing. So it does the bare minimum to report the issue and then stops even its own execution.
There's also a softer variant of the kernel panic called kernel oops that should let the user choose to continue if they think the risk of data corruption doesn't outweigh losing all data currently in memory. But just like the kernel panic, it is handled completely inside the kernel and userspace is frozen until the user chooses to continue.
This is intended for situations where systemd runs into an unrecoverable issue while booting (for example you have misconfigured fstab and a required disk is missing). Without this, you just get thrown into the terminal with some error messages that might not make much sense to you if you don't have a decent understanding of Linux. Now, you get a more newbie friendly message and a QR code that should bring you somewhere you can learn more about possible causes and troubleshooting steps.
Yeah, that makes sense. So it's for the situations where you end up in an emergency shell.
Some better presentation of kernel panic would be nice (which I think is the closest equivalent to a Windows BSoD), but I guess it would require kernel support.
Please let it not be blue! Rather default to Linux black with white text!
Just when I thought I had escaped it for good...
But why deprecate SysV style init scripts? This is super helpfull on things like the raspberry pi (imo)
