Hi
I'm upstream for openresolv and was asked to comment here, so here I am :)

(In reply to comment #2)

As far as the user interface is concerned, they are the same as openresolv was
designed as a drop in replacement for resolvconf.

One of my reasons for writing it :)
Good idea but poorly implemented. No doubt in the future someone will do better
than me, but until then openresolv is the best at what it does.

It's entirely user configurable and quite well documented, but the default is
pretty much this
   $configured $dynamic (exclude dynamics with metrics) $metric $sorted
   $configured is a user defined list, default lo lo[0-9]*
   $dynamic default is tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*
   $metric is numerically ordered and configured by the calling program
   $sorted is just that

So for example, if dhcpcd (which I am also upstream for) works on both wired
and wireless interfaces the wired interface would be given a lower metric by
default so openresolv would prefer this information. However, this is an
extension to how resolvconf works so not much probably uses it other than
dhcpcd right now.
