Integrity of data in a database filesystem. (Score 2)

This database filesystem might have a real advantage in terms of keeping the database records in a consistent state. Remember that in Unix files have arbitrary data. So a journal filesystem tends to keep the meta-data in a consistent state. They don't do much about the application data written into the files. However if mySQLfs had knowledge of the records being written, presumably it could do a lot of the cool stuff done in main frame OS's to ensure integrity. I don't know the VFS interfaces though, so I'm not sure if this is implementable under the current linux framework.
