Hi Gary,

One of the main problems that we have found while investigating the "chroot" 
options was that when the system is running in "init 5" (graphical xwindows) 
and the chrooted program is in place then the user cannot move out of their 
directory from a shell. This also work great for "init 3" (text mode).

The fundamental problem is when you start an application once your window 
manager such as kde has been started. If you start Netscape, or OpenOffice for 
example the the user is free to navigate all over the system and effectively 
breaks out of the 'chrooted' environment.

this is why we have been looking to do it from many other possible directions 
although there does not seem to be any easy method for this.

Cheers,
Lonnie
