Good to know this works.

It just a wild guess, but might it be that your recursor tries to listen on
a specific IP address that is not available at that time yet?
In any case i guess it would be best to also depend on started networking
or whatever that is called in upstart. PowerDNS recursor tries to prime
from the root nameservers upon startup - while i don't think it will crash
when it is unable to reach them enabling it to reach them and other
authoritative nameservers might just be considered best current practice.

best regards,
