Be patient people a deb is in progress with a gui that apllies the patch
and the tweaks (optional)

And i will take a look at the script again to make it only for maemo5

cause when i first made the patch i made it for maemo5 and any linux system
so rc.local is empty cause it is not existed in n900 anyway
but existed in other linux systems
So if you applied the patch in other linux system rc.local will not be empty and the patch will be applied
the most effective part of the patch is .bashrc and the .ashrc

Edit IMO i think it is better to leave the patch as it is cause the creation of rc.local doesn't effect anything else

So the patch can be used in other linux systems
