I am still undecided if it's doing what I want it to do;)  I am also
undecided on the scripts in /libexec/resolvconf/, especially the
ports-related ones.

For dhclient-script I have found that, though not entirely right I
needed

+                if [ -s $tmpres ]; then
                         /sbin/resolvconf -a ${interface} < $tmpres
+                fi

as it killed my resovl.conf otherwise with the empty input; obviously
I should have my defaults in resolvconf.conf probably.

We'll also need a man page describing the basics.  I would love if
there was a simple C interface to use rather than having to go and
handle it independetly everywhere; a tiny lib just wrapping the basic
calls.  Not sure how Linux fixed that?  I'll continue to experiment
with it in various scenarios and I think it's the right way to go.
