Don't stop there, why does Fedora have both "qemu-ppc" and "qemu-system-ppc" and 
so forth? There are many of these, "arm" and "m68k" for instance. On x86 I 
assume that they are both emulated, and they are not two names for the same 
executable or such, so what are they and how to choose which to use?
