Hi,

So you can accomplish the /etc/resolv.conf part today, by redefining the
make_resolv_conf() function in a custom hook in
/etc/dhcp/dhclient-enter-hooks.d/ You could make the function be a total
no-op, and then you have what you want there.

As for default gateway behaviour, that's a bit more difficult today. It is
my longer term vision for /sbin/dhclient-script to be a large collection of
shell functions that can be user-overridden by way of hooks.
