'shutdown' is in group operator, and executable only by root and
operator. Many of the devices are also in the operator group by
default. In a typical organization, you want numerous people to have
operator priviledge, so that they can perform a controlled shutdown
when necessary, but not so many people to have root access. The
alternative of allowing anyone to perform a shutdown is even less
attractive. Even on my desktop computers, I always give the operator a
password, and shell, just in case I get locked out. Of course, I
could always cycle power and Ctl-\ during the fsck, but that's nasty.
