After booting, eth0 is up and dhclient3 is running. However, eth0 still doesn't have an address, see bug #33968, so I have to do an ifdown and ifup to make things work.
I have noticed that after running ifdown, the dhclient3 process is still running. If I just run ifup afterwards, there will be two of them running.
(ifupdown 0.6.7ubuntu7 and dhcp3-client 3.0.3-6ubuntu6)
