I don't think this works in the context of serial console installations, 
and I'd prefer to keep this kind of logic isolated to things like 
/usr/src/release/rc.local instead of polluting the installer itself with 
knowledge of how it is run. Can you think of a way to do it that doesn't 
break serial installations? There's some logic in rc.local already to 
detect the console type.
