I vaguely remember this discussion, but I don't think that it outlined
any long-standing brokenness wrt 127.1, but merely that some implementations
Just Plain Lost (tm), in which case then you don't use it. There was a fair
bit of speculation in the discussion...

Err, no. Just that a lot of resolvers are known to break with them
(particularly in the case of host-up/named-down), and that I always
get infuriated when I find that swapping the order of nameservers
fixes the problem :-) If you want me to dig up examples, send me
personal mail.

Anyway, I think this is all hashed out:

	Don't ever use 0
	Use 127.1 if it works for you and your paradigm is that most hosts
		should look to themselves for their DNS lookups
	Use the primary interface if 127.1 doesn't work for you
	Use the primary interface if you expect lots of people to copy your
		resolv.conf file and want them to point at you and not
		themselves (why you'd want this...)
