In xenial and earlier, apparmor depends on initramfs-tools. In zesty and later, this dependency has been dropped, as explained in the Debian changelog for 2.9.0-3+exp1 and merged into Ubuntu in 2.10.95-4ubuntu1:
* Drop dependency from apparmor on initramfs-tools: the early modules
loading code that needed it was removed a while ago (Closes: #771240).
This is a wrong dependency in xenial as well, which also includes no early boot code. We should drop this dependency, to support building of images with initramfs-tools removed for systems that we know don't require an initramfs.
