There’s been some Friday night kernel drama on the Linux kernel mailing list… Linus Torvalds has expressed regrets for merging the Bcachefs file-system and an ensuing back-and-forth between the file-system maintainer.
Well, yes use-case is key. But interestingly ext4 will never detect bitrot/errors/corruption. BTRFS will detect corrupted files because its targeted users wants to know. It makes it difficult to say what’s the more reliable FS because first we’d have to define “reliable” and the perception of it and who/what do we blame when the FS tells us there’s a corrupted file detected?. Do we shoot the messenger?
