True enough, at least unless you include the ioctl() interface.  Though
there are relatively few shell-programmable interfaces to ioctl(), they
do exist; and of course there are almost no common shell-level tools
that can do their own ioctl()s.

certainly FreeBSD has taken it further without as much resistance.  ;-)

NetBSD has also made more use of it recently too.
