What we really need is devfs. Device cloning itself is really easy, but
to do it right we want a direct file descriptor device interface so
the device can be assigned to the (private) file pointer instead of to
the (shared) vnode. devfs is needed because when we bypass the vnode
the access and modified times will no longer get updated for devices
in a normal UFS based /dev filesystem.
