Just a quick log entry: About ten years ago, I made the switch from Ubuntu to Arch Linux.
Ever since, I have stopped worrying about upgrades. Not even once has an upgrade screwed up my machine. I only reinstalled Arch once in 2011: It was the easiest way to switch from 32 bit to 64 bit. (I got new hardware and my previous Intel Core Duo T2300 did not support 64 bit.) Or maybe I was just lazy, because there is a guide on how to migrate between architectures and it already existed back in 2011.
Virtually all upgrades are totally smooth. My Arch boxes require almost no maintenance other than
pacman -Qdt) if you’re bored.
That’s so much easier than dealing with massive release upgrades.
To all Arch devs, trusted users, the bug wranglers, and everyone else involved: Thank you so much. You’re doing an awesome job!
