I would hope it's more stable. I like s3fs, sshfs, and similar solutions, but it gets wonky in corner cases, like gaps in connectivity. What I'd really like is a kernel-level file system abstraction which: (1) Has capabilities, and unsupported operations fail. If I try to move a log file over to a medium like S3, it works. If I try to write a log file directly to S3, incrementally adding data, it fails. I don't want compatibility kludges (e.g. copying a file down, appending a line, and copying it back). (2) Provides common abstractions (my file manager works on S3 as much as it does locally) (3) Supports all media. The current implementation broke down with NFS and hot swappable media like USB sticks. Having a removable media stuck in an impossible-to-unmount state shouldn't happen. Nor should assorted failures due to connectivity.
