[ovs-dev] [PATCH 32/33] fedora-spec: added systemd post/postun/pre/preun sections

[Flavio Leitner]

The systemd requires some actions when the package is
installed, upgraded or removed. This patch adds the
needed RPM sections with the missing systemd actions.

There is a change in behavior - the service is not enabled
or started by default.
