Yes, me! Just a few weeks ago my Thinkpad ran out of battery mid upgrade (`pacman -Syu`) and got corrupted so bad it caused a kernel panic right after the LUKS prompt. Only took an hour to boot into the live USB, chroot into the disk installation (`arch-chroot`, but don't forget to mount `/boot` afterwards!!!), and reinstall the entire OS with `pacman -Qqn | pacman --overwrite "*" -S -` followed by `pacman -Syyu` (to update bootloader, just in case). Reinstalled the OS and didn't even have to restore a single dotfile. Edit: You may have to update your live USB packages first so run `mount -o remount,size=4G /run/archiso/cowspace && pacman -Syu` (cowspace is a ramdisk so make sure you've got the memory) Edit2: I really hoped "and didn't even have to restore a single dotfile" was enough of a clue that this was tongue-in-cheek. I migrated to Arch a few months ago after two decades of Windows so as far as OS reinstalls go, this was like Microsoft sending me a giant settlement check with triple damages.

You corrupted your kernel. Arch had nothing to do with that, and regardless of the os if you corrupt the kernel you need to reinstall.

  Wow. How’s that a reasonable answer? The OS did a very bad job at upgrading something that should be upgraded in an atomic fashion and blew up on both that and a failsafe boot to previous kernel. Neither should happen.

    Unplug a windows machine, or any os, while its updating and see what happens. Y

      Please point me to where I said windows does a good job, because I must’ve missed writing that.

      Android and ios will survive this. Android uses an A/B partition scheme and will switch back to a working partition if the upgrade failed.

  How do you corrupt your kernel? What leads to that?

  Fedora silverblue can recover from this state. The kernel is just a file inside the OS image. If the latest OS image is corrupted due to a power failure, it will just boot the previous image which is still working.
