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

[Daniel Dickinson]

Package: avahi-daemon
Version: 0.6.30-5
Severity: normal


Because debian now changes the MAC address of interfaces on every boot (for privacy reasons I assume), the IPv6 address for the interface is different on every boot.  Because the IPv6 address is different avahi ends up with a name conflict with the name cached in other avahi daemons on other hosts.  This means hostname.local can't be used to address the host after a reboot because you end up with something like hostname-22 as the avahi name instead of hostname.

This is somewhat problematic because it means you can't have a reliable hostname using avahi, which kinds of defeats the purpose as far as workstation records and libnss-mdns goes.
