I reposted @bluca's FOSDEM talk about soft reboot earlier already. Unfortunately Mastodon doesn't allow reposting with a comment, so let's post the video a 2nd time here so that I can comment on it: I think this talk is particularly interesting as it shows a soft-reboot based online OS update on the actual Azure fleet. And that's not just technically exciting I think, but also a first: that you can actually look over Microsoft's shoulder how they make Azure work. Enjoy!
