Oh, minor point here: I don’t think the upsetting thing was that an experimental filesystem that can only be run on a special fork of the Linux kernel is well supported. It was two things:
- The advice he got on how to achieve this was so simple that he couldn’t believe it was useful or on-topic advice. So he was initially annoyed at receiving (what he thought was) bad advice from someone who (he thought) wasn’t really listening to his problem and (he thought) didn’t understand how experimental
bcachefsstill was/is. - When that simple advice did work, it laid waste to all his overcomplicated plans about how to approach the problem. There might be some playful anger in this, but the experience is mostly delight, like in being amusingly duped by a brilliant magic trick. You find yourself thinking how the hell did you do that, you clever bastard!? It’s a feeling that your expectations of what’s even possible have been subverted. It’s perplexing but it’s also joyful.
Hopefully that makes it a little more relatable.
