Well, it does answer how to workaround problem -- either install
initscripts or remove insserv. But in general, you are in your right
to have this combination of packages on your system.

Since initramfs-maintainer says, that initramfs-tools do not invoke
insserv, another guess is udev/init-system-helpers. Reassigning for
udev.
