>Description:
The "nodev" and "dev" mount options have been no-ops that
have been silently ignored since FreeBSD 5, due to the introduction
of devfs.

In FreeBSD 7, if a user has these options in /etc/fstab,
or does "mount -o nodev", it will result in a mount error,
and that particular mount operation should fail.
>How-To-Repeat:

>Fix:
Remove all references to "nodev" mount option in documentation.
