The basic BDI-4 installation already uses a post-install script to tweak 
certain settings and to correctly configure a couple of essential packages. 
To add another section to the script would be possible, but as has been 
pointed out, an upgrade to ssh could overwrite the X11Forwarding option and 
then we would have complaints of a broken ssh package. My personal preference 
is to keep auto-scripted tweaks to an absolute minimum and document 
additional tweaks rather than forcing them on to everyone.
