Yes, but Dimitri has designs on making linux-kvm a virtual package that
points at linux-generic, in which case amd64 would then regress in the same
way.

Since non-minimal images all have initramfses, something seems to be
treating minimal differently by either removing them after generation or not
copying them to the right place.  If it's wrong to do that, we should remove
that code instead of adding more code.

Also, I have a question about whether it's right for a minimal image to ever
require an initramfs, or if the need for this indicates a problem with the
kernel config.  (Requiring an initramfs increases the disk space
requirements for the image, due to duplication of content between the rootfs
and the initramfs, and therefore makes it less "minimal".)
