The agent is intended to be installed within a QEMU VM guest where a user is likely to not want to have the rest of the QEMU installation within it. Additionally, an initscript, udev rules file, and systemd unit file are added to the package so that the guest agent can start automatically; the former two come from Debian's packaging for qemu-guest-agent.
