> i also dont really get the point of zerofs. Seems like you are building a posix fs on top of s3 that is built on top of a posix fs

That can literally be the stack, but the same argument could be made about object storage itself: it ultimately writes data to local disks, so why not write files there directly?

The value of object storage isn’t just its API. It’s the durability, distribution, failure handling, and capacity behind that API. ZeroFS lets POSIX applications use those properties. Its server and cache are replaceable and the bucket remains the source of truth.

If one machine and its disks are enough for your data and reliability needs, then yes, a local filesystem is simpler. ZeroFS isn’t intended to improve that case.
