The QEMU spec I'm using for virt-ark is very much cut-down and simplified
and doesn't try to follow best practices for packaging [1]

Well if we want to have a RPM spec file for QEMU distributed with upstream
QEMU, then I think it would be better todo what libvirt does[2], and simply
have the real Fedora  specfile kept in QEMU git [3].
