But that's not the point. The point isn't to harden the system against an attacker bent on subverting your name lookups. It's to protect your locally modified configuration file from being overwritten by well-meaning but stupid software programs. (And yes, there are other ways to achieve that, but I've already posted the <https://www.cyberciti.biz/faq/dhclient-etcresolvconf-hooks/> URL in this thread. Oops, I did it again.)
