But they have a filesystem interface. Crucially, this involves
additional interfaces. VC cannot be automatic.
I think our problem is that we look at FV from different angles. I look
at it from the point of view of people who have NEVER used FV, and you

That's certainly a part of it. It's interesting reading this discussion, as

'src/file.c' to '.snapshot/hourly.0/src/file.c' and see what it was like an

Versioning cannot be automated; taking periodic snapshots != capturing
application state.
But I think we have existence proofs of operating systems which do automate
versioning.
It's true that capturing a new version each time a file has been modified and
closed may not be perfect, but if it
