Same problem encountered here - this commit fixed it for SlugOS (which
has its own initscripts which explicitly invoke update-rc.d, thus
causing an obvious build failure): c906fd7faa8517ca565faba90887d10ebb90e092
Basically, adding RDEPENDS="update-rc.d" and
DEPENDS="update-rc.d-native" resolved the issue.

(I glanced at the other initscripts BB files, and didn't change those
because there wasn't an obvious reference to update-rc.d in the recipes
-- I didn't consider the use case you described or I would have fixed
those recipes as well.)
