Calling CoreOS unsuccessful is a massive misunderstanding of the market.
For example, we've gone a step further than CoreOS did and have a fully open-sourced update server, Nebraska (https://github.com/kinvolk/nebraska). We also generate a list of contents and licenses for each build. Here is an example from the most recent stable: https://stable.release.flatcar-linux.net/amd64-usr/2512.2.1/...
https://en.wikipedia.org/wiki/Container_Linux
(for those who don't know, it was renamed from CoreOS to Container Linux)
2. I've always expressed strong opinions in my posts. Sometimes this results in multiple upvotes, sometimes in multiple downvotes.
3. About being "unsubstantive" - I underscored the main concept/rationale for Core Linux, and linked to its Wikipedia page. You could argue that it's not substantive _enough_, but when you phrase it this way it's as though you merely dislike the fact that I repeated the inflammatory term from the article.
Just because people buy snake oil, it doesn't make it a good product.
