You see, the FS process, which implements the file system, *is* a user mode process. Yes, it is loaded with the kernel, but it doesn't have to be -- and in fact it can be run as a regular UNIX process with e.g. System V messages used for IPC in place of Minix messages. And people are working on network file systems which will be user-mode processes. Of course, it remains to integrate it into a useful OS. RMS, are you listening??? -- Brandon S.
