This is interesting news - ubuntu moving to rolling releases.
This is largely what drove me to using arch, as every release upgrade of ubuntu was a goddamn nightmare, and haven't really considered ubuntu outside of purpose-built (and destructible) vm servers since. My love of arch is not without issues, upgrades can be painful at times too unless you're the kind to reboot often and upgrade weekly, but just isn't how I work, so interested how ubuntu fares with the rolling releases.
