I have the assumption that this is related to the fact that the postinst_ontarget script cannot be deleted. With systemd as init manager qemu boots normally for all package classes and the test passes.

I'm afraid you have to look into the hang. Setting 'systemd' is a
workaround that covers up some kind of issue.

I also wonder how the feature is supposed to work in the first place,
if postinst mechanism relies on being able to delete the postinst, so
it's executed only once,
