I don't want C programs mucking with my configuration files.  Period.

It is trivial to move this functionality from the DHCP client itself into
a shell script (or shell scripts) it invokes.  It wouldn't be much harder
to maintain some compatibility with the scripts used by ISC dhclient, by
exporting the same variable names for old and new address, etc.  Roy's
DHCP client would get smaller, and I wouldn't get my ntp.conf or resolv.conf
stomped if I didn't want them stomped.
