Every day is something of an exaggeration, but if you don’t keep a rolling release up-to-date regularly (like once a week), packages start to break. And this gets to be a problem, especially if I don’t keep a computer always on, or if I keep postponing updates because my laptop is not connected to the Internet at the schedule time. There are a dozens reasons why I miss regular updates, but the point is, it should not bork my system if I do miss updates for a while.
