Well, okay, but looking back over the archives it seems like VOP_FCNTL is
meant to be even more specific than VOP_IOCTL---it affects the file
descriptor rather than the file.  The things I want to do will affect the
filesystem as a whole (I mean mount point, not the whole LFS subsystem)
and in particular they probably will not affect the vnode in hand.
Really, the operation closest scoped to what I want is mount, but I don't
think mount flags provide enough flexibility for the sort of operations I
have in mind.
