This page is dedicated to hiding parts of the filesystem from within Nautilus. It is good to do this in environments such as schools, where limited access by normal users to the viewing of underlying operating system files/directories is desired. Please note that this technique is specific to Nautilus - other methods of gaining access to the filesystem, such as through OpenOffice "Open/Save" dialogs, the terminal, and other programs that do not use Nautilus to browse the filesystem are not affected (yet).
Doing this is easily accomplished by creating (as root) a file called .hidden in whichever directory you want to hide files/subdirectories in, which contains, one line at a time, a list of each file and/or directory you want to hide.
For example, I have created a file called /.hidden:
cd / sudo vim .hidden
bin boot cdrom dev etc initrd lib lost+found media mnt opt proc root sbin srv sys tmp usr var initrd.img initrd.img.old vmlinuz vmlinuz.old lib32
