Comment 6 for bug 249038

I can reproduce the problem with darkstat 3.0.712-1 on Jaunty. The problem is (piping darkstat --verbose --no-daemon through /usr/bin/logger at boot time):

  error: pcap_open_live(): eth0: That device is not up

Changing the boot order via update-rc.d doesn't fix this problem for me. darkstat needs to be started after NetworkManager is done configuring eth0.

You'll notice even e.g. ntp is started prior to NetworkManager, despite /etc/init.d/ntp containing:
  # Required-Start: $network $remote_fs $syslog

NetworkManager restarts ntp after the interface comes up, via /etc/network/if-up.d/ntpdate
