Had no clue of the original quote, hah. Thanks for letting me know! :)
And I especially agree with the multi-core comment. We need filesystems as full-blown ACID databases, like 10 years ago now.
Surely it can't be so difficult to have a K/V store with ACID semantics and give it a filesystem emulation layer so people can use all the normal coreutils like `ls` and `cd` etc. But then also add a little extra API that allows for locking, transactions and all the good stuff?
Will nobody step up?...
>Few people know the complete quote: >"Everything is a file — the worst possible primitive"
Especially in a multi-core world, you need to know a lot of Unix(/Linux) arcana to write a program that ensures ACID-like properties for files. (And this need applies to almost any program that writes to a file.) If filesystem APIs were redesigned tomorrow, they would be quite different from what we have today.
