[YOCTO #1070].
The pkg_postinst_dpkg seems buggy, e.g., for dpkg-native,
${IMAGE_ROOTFS}/${sysconfdir}/rcS.d doesn't exist.
I think OE's version(do_install_prepend) at
http://git.openembedded.org/cgit.cgi/openembedded/tree/recipes/dpkg/dpkg.inc
is correct, so let's change to OE's version.
And, bth dpkg and update-alternatives-cworth supply
/usr/bin/update-alternatives and this causes conflict. e.g., bug 1070.
We can resolve the issue by ask dpkg not to supply the binary.
