This is really neat, but when I saw the headline I got excited that it was something I have been looking for / considering writing, and I figure the comments here would be a good place to ask if something like this exists:

Is there a FUSE filesystem that runs in-memory (like tmpfs) while mounted, and then when dismounted it serializes to a single file on disk? The closest I can find are FUSE drivers that mount archive files, but then you don't get things like symlinks.

Why does it have to be in memory?

I’m sure you’re already aware of this, but there are all kinds of very real scenarios that could lead to corrupted data if you’re only flushing the buffer upon unmounting.

Sounds like you’ve got an interesting problem you’re trying to solve though.
