Network services started before NIC UP.
I have a problem that services are started on a server I manage before
link is UP. This leads to some services failing, or not bound to every
addresses :
here is an excerpt from the logs :

You can see that ntpdate is started before network is ready. What is
more annoying is that I get an IPv6 prefix through dhcpv6 prefix
delegation, and even though the logs do not appear here, it seems the
dhcpv6 request is sent (by dibbler-client) before NIc is UP, which leads
to my prefix not being routed to my server.
Against which package should I report a bug, and is there a workaround
for next reboot ?
Thank you.
