That is really funny: inside of this ramdisk is a tmp dir, with 279 MB
inside, where the biggest part is the squashfs image and some files
which are generated after start of installation.

That means that the squashfs is packed inside a initramfs during
installation? I don't get the idea because we *have* a running system
with a initramfs, that is the primer for the whole boot.
