Public bug reported:

Boot process is delayed with the message on screen "ubuntu 11.10 booting
system without full network configuration".

Some processes did not start (eg nmbd, mediatomb). They appear to be
waiting for an event, in nmbd's case: start on (local-filesystems and
net-device-up IFACE!=lo) .

Some status checks:

root@u01:~# status network-interface INTERFACE=lo
network-interface (lo) start/running
root@u01:~# status network-interface INTERFACE=eth0
network-interface (eth0) start/running
root@u01:~# status nmbd
nmbd stop/waiting

So, it seems that the prerequisites for nmbd are running, but nmbd seems
to be waiting to start.

Looking at the code in network-interface.conf:

pre-start script
    if [ "$INTERFACE" = lo ]; then
        # bring this up even if /etc/network/interfaces is broken
        ifconfig lo 127.0.0.1 up || true
        initctl emit -n net-device-up \
            IFACE=lo LOGICAL=lo ADDRFAM=inet METHOD=loopback || true
    fi
    mkdir -p /var/run/network
    exec ifup --allow auto $INTERFACE
end script


It emits an event when lo starts, what emits an event to notify that eth0 
started?
