Interested to know how optimistic DAD worked out for you. I'm not sure why, but I'm still getting services failing to start at boot with optimistic DAD.

In specific, on a VPS back by SSD storage, running OpenSMTPD on Arch Linux, I'm still getting errors regarding the bind address being unavailable.

Weirdly enough, adding sleep times (in the order of 5 seconds) before service start or restarting the service after a time-out did not help (not that they would be acceptable `solutions'), but disabling DAD did. I suspect there is more going on that I don't know about, because I can't explain these observations.
