COW and volume management?

That can be hard one to categorize :) Some people may think everything is fine, and maybe they're right, maybe they're not - and it may not be clear until it's too late.

But I do not think you can look at the kernel community's track record on filesystems and call it a smashing success. There are lessons I think the community has yet to learn. When you see me talking harshly about those things, it's not because I'm trying to be negative or tear the place down - but sometimes people do need tough love.

That thing that makes me happy is just when I see that people are learning, or at least willing to learn. All problems are solvable - in engineering, and programming especially - as long as we're facing up to them.

But yeah, I am happier since the split, and watching the bcachefs community grow and turn into something really special has been a big part of that.
