[Pkg-utopia-maintainers] Bug#637734: avahi-daemon: new debian changing MAC means IPv6 address differ = name conflict on reboot

[Daniel Dickinson]

Correction.  This appears to have been the result of using service
cookies.  Although maybe it's the combination since the MAC does keep
changing.  In any event by removing service cookies option on all hosts
the duplicate entries don't occur. (i.e. before I as getting
hostname-2, hostname-3, etc each time I restarted avahi).
