Is there any citation to support this? I’ve run arch for 11 years, never once on that same computer did I have to reinstall the OS. On the rest that have been running it for 2y and 5y they’ve never had that issue, nor instruction.
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.
For the average user of a hand held gaming console you may as well tell them to pop the back off and replace the chips on the PCB.
At most you could tell them to hold a button combo to factory reset but ideally you would want some way to roll back the whole OS state to the previous working version. Silverblue allows this to happen in a fairly elegant way by making the OS an image file and mounting it as read only so a roll back is simply mounting an older image.
I'm sure you could imagine countless ways that a update could possibly break things.
