I use attended sys upgrade. I've been using OpenWrt for the last 7 years, but I've noticed that attended sys upgrade often fails at release time. And there are often point releases shortly after. I'm just skeptical that their infrastructure would handle mass auto updates at release time. I usually wait a few weeks after release until the masses have reported various device specific bugs before I upgrade.
