Turning a Ubuntu install into a Window terminal server dumb terminal

I've written a quick script to term a clean Ubuntu (I'm using 9.04 netbook remix) into a dumb terminal to connect to a windows terminal server.

You can use it like this:

wget http://sgenomics.org/~new/term.tar
tar xvf term.tar
sudo ./termsvr MYTERMINALSERVERNAME MYDOMAINNAME


Under the hood, the script looks like this:

if [ $# -ne 2 ]
then
echo "Usage: `basename $0` "
exit 1
fi

apt-get -y --force-yes remove gnome*
apt-get update
apt-get install rdesktop
cp ./rc.local /etc/rc.local
sed "s/\*SERVERNAME\*/$1/" ./xinitrc > ./xinitrc.fixed0
sed "s/\*DOMAINNAME\*/$2/" ./xinitrc.fixed0 > ./xinitrc.fixed1
cp ./xinitrc.fixed1 /etc/X11/xinit/xinitrc

where xinitrc contains:

#!/bin/bash
# $Xorg: xinitrc.cpp,v 1.3 2000/08/17 19:54:30 cpqbld Exp $

# /etc/X11/xinit/xinitrc
#
# global xinitrc file, used by all X sessions started by xinit (startx)

while [ true ]
do
rdesktop -f *SERVERNAME* -d *DOMAINNAME* -u "" -k en-gb
done

# invoke global X session script
. /etc/X11/Xsession

and rc.local contains:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

startx

exit 0
