[ovs-dev] missing log directory on rhel?

[Ben Pfaff]

The install guide here:

    http://n40lab.wordpress.com/2013/06/03/centos-6-4-openvswitch-installation/

shows unexpected startup errors:

    #/etc/init.d/openvswitch start
    /usr/share/openvswitch/scripts/ovs-lib: line 49: /var/log/openvswitch/ovs-ctl.log: No such file or directory
    tee: /var/log/openvswitch/ovs-ctl.log: No such file or directory

which imply that our RHEL packaging fails to create
/var/log/openvswitch.  Does that make any sense?  (Maybe we need to list
/var/log/openvswitch at the end of openvswitch.spec.in?)

Thanks,

Ben.
