My distro is based on linux from scratch, there, the network config by 
default starts dhcpcd for every device that is configured to use it. 
Maybe I will discuss this on their list, but for the moment I guess it 
is simpler to setup networking if left like this (no editing of config 
files needed).


Also, I have a couple of routers that do dhcpcd on the first physical 
interface and provide dhcp via dnsmasq on the other two interfaces. I 
think, explicitely specifiying the interface there is also a good idea.
