Yeah, that's about 95% of it. I don't think it has a service yet though?

Here is my .bbappend. It probably isn't perfect or bug free, but working 
on my dora builds. I think I ripped the scripts out of the debian 
packages and then fixed anything necessary to make them work with busybox.

cat resolvconf_1.74.bbappend
# Added by Dean to fix issues in resolvconf recipe

# look for files in this layer first
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

SRC_URI += " file://fixpath.patch \
          file://resolvconf.init \
          file://netresolvconfdown \
          file://netresolvconfup \
          file://pppresolvconfdown \
          file://pppresolvconfup "

inherit update-rc.d

INITSCRIPT_NAME = "resolvconf"
INITSCRIPT_PARAMS = "start 39 S . stop 41 0 6 ."

# add list-records script, its missing in distro
# add volatile resolv.conf - package maintainer didnt??!@?!
# Add startup/shutdown script
FILES_${PN} += " /lib/resolvconf/list-records "

     install -d ${D}/lib/${BPN}
     install -m 0755 bin/list-records ${D}/lib/${BPN}/
