I'm in danger of claiming more knowledge than I have, but on this 
system, running Ubuntu and using dhclient, there's  a big script in 
/sbin/dhclient-script which does all stuff, include ifconfig and route. 
Maybe that's an Ubuntu or NetworkMananger thing, but the copyrights at 
least imply that it's derived from a generic script.

/sbin/dhclient-script seems to be a master script which invokes the 
directories full of small, package-supplied ones.
