I don't see a difference but I see what you mean with "on start" which I =
treated
as "on boot". The answer unfortunately is - DAD is not supposed to take =
that
long that it would matter, so the NIC drivers are probably silly or are =
required
to do silly things. I wonder if you might even see a DOWN/UP cycle.
The workaround you can apply is to use the prestart option to the jail =
to add that
sleep 1 you need and let the startup script configure the IP addresses =
for you.
See jail_exec_prestart<n> in man 5 rc.conf.
