I tried, but I couldn't figure out where this came from.

Those custom initscripts are not in our own layer. It's in a layer we build upon. So it's a bit more complex.

Anyway, what we have there is the following. In the machine conf file there is:

VIRTUAL-RUNTIME_initscripts = ""

This replaces the default meta/recipes-core/packagegroups/packagegroup-core-boot.bb:

VIRTUAL-RUNTIME_initscripts ?= "initscripts"

So I assume that's how they remove the initscripts package. And then in the image recipe they have:

PACKAGE_EXCLUDE += "initscripts-dev"

But for some reason this doesn't work for us. It fails with this error:

ERROR: Unable to install packages.

I'm not even sure whether PACKAGE_EXCLUDE is supposed to be used from an image recipe, because the documentation refers to local.conf. So that might explain why it doesn't work.
