I’ve had arch “break” on me about 4-5 times. Most of the time it is issues regarding Nvidia drivers being updated (usually just chroot and reinstall/reconfigure drivers fixes it), but the others were mostly my fault (I’m often pretty lazy about making sure my system is up to date, and expect some breakage if I update only about every couple of months on a pretty customized system without looking to make sure nothing will cause an issue).
