Hi Rutger,

	I don't really know enough about the alternatives system to be able to do 
too much with this to be honest, and don't really have the time to find out :
(. I agree that in a perfect world that would be the way to go, but my limited 
understanding gives me a few concerns which maybe you can address :).

- I thought that alternatives was debian specific. I hoped to get a script 
together which had a chance of working in most distros ( ok, I used upstart 
but this is at least more generic and can simply be swapped for a traditional 
rc.d script. )

- The creation of the appropriate config seems a little involved, some very 
long update-alternatives --install command? Maybe some dpkg divert command to 
prevent new installs of mesa-gl putting things back?

- I wasn't sure that the NVidia installer would play nicely with the 
alternatives system - i.e. if you re-install or update the NVidia drivers, 
would things still work without re-doing some of the alternatives stuff?

	The aim of the script was just to knock up something very quickly which 
had a hope of being fairly user-ignorable once it was in, hence the way it 
looks for "nvidia" in a file to try to determine which files are installed in 
case they're updated etc. etc.  As you can tell, I don't really know enough ( 
actually virtually nothing! ) about debian alternatives to even test what 
you've done below.

	Sorry :(.

Adam.
