[Bug 885909] Re: Boot process hangs in Ubuntu 11.10 server after upgrade

[Stéphane Graber]

Ok, I'm marking the bug in ifupdown as invalid because there isn't
anything to fix in ifupdown.

As for boot logging issues with upstart, it's a known issue and upstart
1.4 that will ship in 12.04 has a feature called "job logging" that will
populate /var/log/boot.log and /var/log/upstart/<job>.log with whatever
output the upstart job gave.

Title:
  Boot process hangs in Ubuntu 11.10 server after upgrade

Status in “ifupdown” package in Ubuntu:
  Invalid

Bug description:
  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 at u01:~# status network-interface INTERFACE=lo
  network-interface (lo) start/running
  root at u01:~# status network-interface INTERFACE=eth0
  network-interface (eth0) start/running
  root at 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?
