[Bug 458904] Re: When installing a node, euca_find_cluster fails to locate the cluster controller if instances are running

[Mathias Gug]

The workaround discussed by Thierry and Martin in comment 11-14 is
working as expected:

1. Update avahi-daemon upstart job to use /etc/eucalytpus/avahi-
daemon.conf if is there:

+       exec avahi-daemon ${opts}
+end script

2. Ship /etc/eucalyptus/avahi-daemon.conf in the eucalyptus-cc package
that disables address publishing:

publish-addresses=no

3. Add an eucalyptus-cc-publication-ip upstart job to publish the CC
IP/hostname mapping:

exec avahi-publish -a $(hostname).local $CC_IP_ADDR

With these changes, running new instances with public IPs doesn't change
the IP address returned by euca_find_cluster for an NC iso installation.
