I have been using unstable on desktop for at least 15 years. Every time a new stable was released that would cause a month of just staying off updates till things stabilized. Recently it’s not even had that issue.
I’ve had to pin a package or two in that time, but unstable has been rock solid otherwise. I even run it on my server.
The orcs of the misty mountains are called goblins. I think Tolkien used the terms interchangeably.
