Yes. However, I still question the "filesystem" part.
Technically, what I think any persistent storage should aim for is to be a "journal" - not a filesystem. It's most useful as a temporary area for data _before_ that data actually hits the disk, and once it has hit the disk (or has been picked up by a network syslog server, of course), the usefulness of the persistent storage immediately vanishes.
So I don't really mind having a filesystem interface to that (the whole "everything is a file" model), but I think it can end up confusing people about what this thing is useful for. I fear that people will try to write to it from user space as some kind of mini-filesystem, and that seems pointless.
