That’s not my experience - have been using arch for around four years and it broke only once by not letting me log into the system after I failed to update pam configs after the system upgrade.

Dunno, during 8ish years I have only hada couple of minimal problems due to updates (and the solution was promptly available on Arch homepage). Can’t speak for other, though.

We’re using Arch 2

(No it doesn’t, it just has some bugs here and there, e.g. my media keys don’t work after a couple days of uptime (gnome). I stopped actively looking for and reading the release notes years ago as it just works… and if it doesn’t, I still have a btrfs snapshot from before the update)
