What if you don't care about caching, what if you just want a filesystem that works? Bcachefs is not just targeted at caching — it's meant to be a superior replacement for ext4, xfs and btrfs. We intend to deliver a copy on write filesystem, with all the features you'd expect from a modern copy on write filesystem — but with the performance and robustness to be a very viable replacement for ext4 and xfs. We will deliver on that goal.
