Not sure if this is intended behaviour, or not.

Every time I start an interface using wg-quick with the SaveConfig = 
true it reloads all the previous, saved, IPv6 link-local addresses plus 
generates a new one.  So the first time the interface is started there 
is 1 link-local address.  The next time, 2.  Then 3. Then 4, etc. etc.

Cheers.
