I am writing a stackable file system which requires some database file. I am thinking of taking it as mount time argument and then reading it's content into private field of superblock of mounted FS. Precisely I intend to do this:
mount -t wrapfs -o pattdb=database.db /some/mounted/point /mount/point
Here I'm having problem in figuring out where does(in what field of FS does it reside) the file database.db go?
