Remember, every interface has multiple addresses in IPv6.  While I
don't know if Linux behaves similarly, for Windows, the privacy
address is primarily used for outbound connections.  The MAC-derived
IPv6 address is also still active, and is the one registered
automatically in DNS, so you would still reach your kit via stable
addresses (well, as stable as the physical network interface).
