I'm also forced to relegate the chattr solution to the end of the page, and couch it in caveats, because some people think that it's wrong. They can't say WHY it's wrong, of course. Maybe because it's too simple and effective. I dunno.
How about the fact that it just solves the symptom but not the real problem?/etc/resolv.conf does not change by itself, some tool must be making the (possibly undesired) changes, so in most cases, I'd say it's better to configure that tool to stop changing resolv.conf, or to add the nameservers you want instead of whatever the tool auto discovers. Or perhaps you don't even need that tool (in a server with static IP, for example).
I'm not saying that chattr +i should never be used, but it should be the last resort, and the user should know what they're doing and possible consequences.
