For users, the OS is a black box, it provides services of FS. The OS should hide differences of each FS, so usermode app can run happily on every FS. For the same reason, OS should return the same error, no matter what FS it comes from. Users only care about the interface, not the implementation. So, OS should _AT LEAST_ make the interface clear(here means the syscall should return a definite error)
