[avahi] Preventing avahi from dropping link local addresswhen routable address is configured

[Williams, Ksatria G]

Hi Lennart,
  It turns out this bug was already reported as Ticket #209. I used the
exact same solution in adding force bind to the routable address
configured condition as was already reported there. Sorry for not
checking first.

--force-bind should do exactly what you want.

if it doesn't it would be a bug.

Is it possible that you are misinterpreting the output of ifconfig?
Please make sure to use "ip addr" for looking at the IP
configuration. ifconfig is obsolete and shows interfaces with multiple
addresses incorrectly.
