I understand that the utils themselves are still installed regardless, 
but in order for the 'patch' command to have something to patch against, 
doesn't 'src' have to be installed also? Otherwise, are you saying that 
the sources to all the system bits are always installed? And if *that's* 
true... then what the heck is 'src' installing then?
