Quote: "you could lose data"

Quote from webpage: "The COW filesystem for Linux that won't eat your data"

Quote from webpage: "It's the job of the filesystem to never lose your data: anything that can be repaired, will be."

Quote July 2025: "I've been digging through the bug tracker and polling users to see what bugs are still outstanding, and - it's not much. So, the experimental label is coming off in 6.18."

I was a big fan of bcachefs and was looking forward to deploying it across ~100 machines in production. Unfortunately, the removal from the mainline kernel has seriously undermined its credibility for use within a company environment.

A filesystem needs time to mature, and that's fine — but the official webpage should clearly display a warning that this is still experimental and that its long-term support situation is uncertain. People evaluating it for production use deserve to know what they're getting into.

Would have loved to use it.
