[FreeNX-kNX] Little bit of recoding :)

[Marcelo Boveto Shima]

Probably you will want to hack on "node_start_applications()" function at
the
"Startup the application" session.

Something like:
       if [ "$user" == "guest" ]
       then
               NODE_APPLICATION="firefox"
       fi

just before the app invocation line:
DISPLAY=:$display $NODE_APPLICATION
>>"$USER_FAKE_HOME/.nx/C-$sess_id/session" 2>&1 &

Changing NODE_APPLICATION just before it will be called ensures you that the
session will
not be called with something like Xsession.

Regards.
