Comment 9 for bug 1980421

I have seen this as well, and some tweaks to use OVN_RUNDIR on a number of lines was necessary, as mentioned in #6.

Part of this is due to this line in install_ovn():

  sudo ln -s $OVS_RUNDIR $OVN_RUNDIR

On my test system I had already installed OVS and OVN packages, so it is making the symlink in /var/run/ovn:

/var/run$ ls -l ovn
total 20
lrwxrwxrwx 1 root root 20 Oct 12 21:34 openvswitch -> /var/run/openvswitch

It should have made /var/run/ovn -> /var/run/openvswitch

I'll send a patch that I hope will address the issue.
