I was using this solution for several years, but I prefered to use
totd. Since I thought this was overkill, I mode the patch.

Not only dhclient updates resolv.conf, but ppp, mpd and perhaps others
do. I'm using dhclient and ppp on my laptops. Sometimes, I use
DHCPv6, too. So, I need such setting for each applications. It is
messy to setup a laptop.
