Re: fix for nullfs users

[Andrew Pinski <pinskia@physics.uc.edu>]

In Linux a null mount is called a bind mount.
It means you can remount a file system under another directory,
it is very useful when it comes to chrooted web servers and user
home pages if you want to keep their home directory and web page
on the same file system.

It is also very useful when you export a directory at one mount point
and you want to mount it locally at another.

Thanks,
Andrew Pinski
