Generally there's nothing wrong with running "rpm" as quoted above (and it
has been done successfully many years ago), _but_ with the availability of
some chroot build-systems, we need to allow for an incompatible pair of
RPM versions for host-and-guest based installations. Without a guarantee
that the guest-RPM can query the host-RPM database, running "rpm" in a
spec file may break any time.
