We don't want to put it in the squashfs, because it's installed conditionally. In any case, this installation used debootstrap rather than a squashfs. Since it's a network install, the presumption that packages can be installed from the network is reasonable.
I suspect that the bug here is actually that network configuration is copied into /target too late to be used by the apt-install queue processing in base-installer.
