While i don't particularly like the notion of the 'cpu' keyword (i can
think of no real reason for having it around)...

I sort of _do_ like the notion of a 'filesystem' keyword...

(1) it'd be nice to throw away vfs_conf.c completely, and
    generate the contents as necessary.

(2) it'd be nice to have a standard, single entry point for
    configuring each file system, including e.g. doing the right
    thing which each fs's vnode ops vectors, etc.



(1) is nice, because vfs_conf.c really is a bit of historical baggage,
anyway, and

(2) is nice, because it's make LKM'ed file systems look a bit nicer,
at least in my opinion.
