This will break my network. I would like to see the sysctl loading issue fixed before this is merged so it is possible to override back to what I had before.
I'm just going to mention that I had a lot of trouble using privacy extensions on networks with changing prefixes (as it is common for Germany).
Essentially what happens:
- On a prefix change, new temporary addresses will be generated for an interface. These are the newest addresses, so they will be used.
- Old addresses are kept for a while for open connections.
- After an address runs out of its lifetime, a new address is generated.
- If that happens to be an address of the old prefix, this one will be the default address and now.
