Ah ? why is that needed for /tmp ?
In the default configuration, X clients connect to the local X server
via a named pipe in /tmp. That is what DISPLAY=:0 means. You can also
use a network connection (DISPLAY=localhost:0), but that is usually
disabled for security reasons, and not quite as fast as a pipe.
In the end, most UNIX servers are accessed via named pipes. So if you
want to use these servers, you have to find the pipe and make it
available to the chroot environment. MySQL for example puts the pipe in
/var, which is quite a pain.
