Boot File System (BFS) is a file system used under SCO UnixWare to allow the bootloader access to the kernel image and other important files during the boot process. It is usually mounted under /stand and corresponds to the slice marked as "STAND" in the UnixWare partition. You should say Y if you want to read or write the files on your /stand slice from within Linux. You then also need to say Y to "UnixWare slices support", below. More information about the BFS file system is contained in the file <file:Documentation/filesystems/bfs.txt>. If you don't know what this is about, say N. To compile this as a module, choose M here: the module will be called bfs. Note that the file system of your root partition (the one containing the directory /) cannot be compiled as a module.
